Problems Sending Email – Receiving is Fine

If you are unable to send email, but can receive you should first verify that you have your email client configured properly. Below are the SMTP SSL and Non SSL settings. you should use one of the following:

SMTP Settings
Non SSL Settings
SSL Settings
Incoming Server:
Outgoing Server:
Username: Your full e-mail address
Password: Your e-mail account password
Incoming Port: POP3 110 or IMAP 143
Outgoing Mail server (SMTP) Port: 587
SMTP Authentication Required
Secure Authentication or SPA needs to be turned off
Incoming Server:
Outgoing Server:
Username: Your full e-mail address
Password: Your e-mail account password
Incoming Port: POP3 995 or IMAP 993
Outgoing Mail server (SMTP) Port: 465
SMTP Authentication Required
Secure Authentication or SPA needs to be turned off

If you are unsure how to make the above changes, we recommend reviewing our Getting Started Guide: Email.

Port 25 blocking

If you cannot send mail, the problem is likely a restriction by your ISP (Internet Service Provider) as many block the normal sendmail port 25, due to their own security concerns. This can be the case even if sending was working recently as some ISP’s roll these changes through without warning.

To give you an idea of how common port 25 blocking is, we’ve included below links to a few major ISP’s and their online documentation regarding port 25 blocking:

Comcast: Why is Port 25 for Email Submission Not Supported?
Verizon: – Re-configure Your Email Settings to Send Email

Checking if Port 25 is blocked

For the average user, the easiest way to find out if port 25 is being blocked is to contact your ISP and ask them. For the advanced user, we’ve included directions below to test port 25 blocking via the command line.

To test if port 25 is blocked, open your command line on your local computer. For windows users, you can access this via start > run > cmd. Mac users can use the “Terminal” application. Once on the command line, type: (Note! Be sure that you replace with your actual domain name)

telnet 25

Please note: Telnet is disabled on newer versions of Microsoft Windows. If you receive an error similar to,”Windows cannot find ‘telnet‘”, you may need to enable telnet. Please see our article on Enabling telnet on a Windows computer

If you get no response or a failure, port 25 blocking is the likely issue. It is NOT port 25 blocking if you receive a response similar to this: 220-We do not authorize the use of this system to transport unsolicited, 220 and/or bulk e-mail.

Port 25 blocking – Fixes

If your ISP does block port 25, you can work around it in either of three ways:

The Preferred Solution

As your ISP is blocking port 25, the preferred solution is to use the outgoing mail server provided by your ISP. As each Internet Service Provider has different settings you will need to use (such as username and password, smtp server…), you will need to contact your ISP for the correct settings. We do have alternate solutions to this which involve going over port 465 or 587 instead of 25, however if your ISP begins to block 465 or 587 in the future, you will once again be unable to send email.

Alternative Solution #1

Beginning in late March 2010, we are updating many of our servers to run SMTP over port 587 as well as port 25. If your ISP is blocking port 25, simply change your SMTP port number to 587. This setting is usually found in the advanced settings of your email client. Please see the end of this article for more details.

Alternative Solution #2

Use the secure, or SSL, port for outgoing mail. This will involve selecting the setting “this server requires a secure connection (SSL)” in your mail program. You only need to make this change for the outgoing mail server. Once you check that box, then change the port listing from 25 to 465 and save the changes. These settings are usually found in the advanced settings of your email client. Please see the end of this article for more details.

You will also want to change the outgoing server name to, secure## being the secure alternative of the actual server you are on. For example, if your Welcome Email states that your account is on, your outgoing server name should be

If you are unsure, please tech support. This option will work in most cases, however we cannot guarantee that your internet service provider will not some day in the future begin to block port 465. Below are instructions to change the ports for the most common Email Clients.

Thoughts on “Problems Sending Email – Receiving is Fine

    • I’m sorry to see that you are unable to send emails. Is there a particular step in this guide that you are experiencing difficulty with?

  • Hi i am un able to send emails to any addres.this is the message i get Message not sent. Server replied:

    Requested action not taken: mailbox unavailable
    550 Account currently blocked for sending to too many
    invalid recipients

    Kindly assist it almost 1 and half months now

  • I am the secretary of a local historical society and for years I have routinely bulk emailed (BCC) about 110 addresses with information about upcoming events, dues reminders and such. Within the past week or so, I have been getting pop-up notices that I have too many addresses for one email. Is this a new limitation imposed by AOL? Is there a way I can increase the number of allowable addresses? I have worked around the problem by splitting the mailing in half but this is an inconvenience I would prefer to avoid.Thank you for any help/suggestions.

    • Hello. Unfortunately, AOL does not disclose their limitations publicly. This very well may be a limitation imposed by their servers. It is common to impose limitations on the number of recipients in one email to prevent the server from being blacklisted/identified as spam. Breaking up the emails and sending to a smaller number of recipients is the only way around the limitation.

  • I have recently bought wix to host our website using your domain, and have linked it through name pointing. it then gave me an option to use g suite to make a new email which is the current one we are using, however after making the switch to gsuite with our new email the old one doesnt send or recieve messages and when we send emails to it, it claims there isnt a e-mail with that address or some other error. our new email (info@****** currently works with gsuite, however webmail and the old email iman@****** doesnt work. it would be great to hear back from you. 

    Iman Madrasah

    • Considering that the domain is pointed away from our server there is nothing we can do to affect the situation, I suggest contacting Wix or Google support specifically for help with configuration of your DNS records.

  • I have corporative e-mail: **************. But more than 10 days I can’t send emails from that corporative mail adress to the different mail adress on gmail or yahoo. All mail are return without sending. How I can to do?


    Best regards

    Nazim Mustafazade

    • I recommend reviewing the bounce back information that is returned when you attempt to send email from that address. That is the only way to determine why the email is not allowed to send.

      If you are a customer of InMotion Hosting, I recommend contacting our Technical Support to assist you with your specific account privately.

  • hey tnx for the article , but this isn’t helping me

    i  have webmail with domain my isuue is i can send messages succfully but its not recive the reciver

    i checked all your soluation still not working :????


    • If you are not receiving email then your domains MX record is most likely not pointed to your server. You should check to ensure your MX record is pointed to your server and that your MailExchanger setting is set to local.

  • Hi,


    i have recently configured SMTP in my personal set up win 2012 r2, but i m not able to send test mail to my gmail. i have changed outboundaries port to 25, 587 as well. Please advise. Thanks

    • Sorry for the problems with the email client. If you’re having problems with it, make sure to double check and see if you’re using the correct ports. 25 and 587 are the non-secure ports. If you’re using the secure settings, then the port should be 465. You may need to speak with support provided for the email client that you are using.

  • I have had same problem today. The outgoing email was not working in my MS outlook, 
    The reason was not becaues of the port settings. But infact, there was auto Avast Antivirus program downloaded and installed in the computer. Without me knowing. 
    I think it came together with Ccleaner . 
    After I uninstalled that. it worked. 

    Last time i had problem that windows security auto update didnt work properly and kept updating itself over and over without sucessfully finishing. the problem was that my lenovo machine came with Mc Afee anti virus even though i didnt buy or activate it. It kind of created this issue. after uniinstalling it, the things were fine. 
    But to understand that, I first tried everything even formatting and re-installing windows. 

  • I tried the settings and it didn’t work. the problem is i can’t send or receive from emails on the same domain using outlook but i can send and receive using web… Also NOTE that i can send emails to email addresses on other domains successfully on outlook. 

    • If you are still having trouble after running through these settings, you will likely need to contact our Live Support team. They have access to server logs that may be able to provide more information about the issue you’re having.

    • When you are trying to send an email to,,, or if the email fails then you should be receiving a bounce-back message from their email server. This is standard protocol between email servers. It’s possible that the bounce-backs may be getting filtered on your end. We need those bounce-back messages in order to determine why your sent email are failing. If you wish have this issue handled in private, then please submit a ticket (with the bounce-back) to our live technical support team. They can also test sending emails from your server. You can find their contact information at the bottom of this page.

  • In the last day or so I have developed difficulties in sending emails – no problems with receiving emails. What should I do?

    • Follow the troubleshooting steps provided in the article above. If you still have problems, then make sure to provide information on a bounce-backs or error messages you may be seeing when sending your messages. Provide this information in a verified support ticket to our live technical support team. They can look into the matter in more depth for you.

  • Up untill a few days ago my Copier and CCTV DVR were sending out Email when ever required too.. Never had a problem with them.Talking years. Then all at once quit. Same day both of them. Have them set up SMTP. Changed no setting. The only thing I did that day was go into my Router and port Fowarded a new adittional DVR. Pretty sure I didnt change anything else in the Router. I tried everything. Im going to reset the router back to its originial setting tomorrow and start fresh. I have done this many times setting up this kind of stuff. Im not Mr IT guy> could there be a virus in my PC flooding spam out my network. Went as far as to shut down all the PC’s on the network except for the server. I had to keep that running. Shutting that down tomorrow with the rest of the PC’s. Check with comcast and asked them to look at there end and there settings. They didnt see anything. Everything else seems to be acting normal on the network. I have all the settings correct in the SMTP settings. Anybody got any advice, feedback.  Tried and Thanks for any help

    • In regards to tracking down possible spamming going on, I recommend using our guides on locating spam activity in Exim and finding spam script with Exim. They should help you identify if there is spam being sent out from your server. As far as the SMTP you should use the SMTP for the domain that you are sending mail from. For instance, if you are using an email address issued by AOL or Google, you would use or (or whatever SMTP hostname they advise). The main point is that a domain needs to be authorized to send via the SMTP hostname’s server, otherwise it will be rejected. I hope this helps!

  • I am having 587 authenticaiton enabled for sendmail. Infect i am having two ports running 25 and 587. I am able to route through 25 not through 587(error relay denied) can you help me figure out what configuration i should change in sendmail to get this working. please advise.

    • It sounds like you are working with opening and closing ports, but I’m not sure what you are trying to accomplish specifically. Are you having trouble sending email? Which client are you using? What kind of troubleshooting has been done so far?

    • Hello,

      Emails can be bounced back for several reasons. We have an article here that explains how to read the bounceback to see why your messages are being bounced and solutions on how to correct that. You can also contact technical support and they will be able to help you figure out why the messages are bouncing too.

  • Hi,

    Outgoing Mail server (SMTP) Port: 587

    Just changing  outgoing server from 25 to 587 worked perfect for me.

    Than you so much,





  • Until a week ago, my sending email on both my PC and laptop was working fine.  Now it won’t work, and I get the following message when trying to send on either device:

    503 Valid RCPT command must precede DATA

    I have checked the Outlook settings on both devices and they are identical to those you recommend – the outgoing server requires authentication and uses the same settings as my incoming server and I’m using port 465.  What to do, please?

    • Hello Norman,

      Sorry for the problems with your Outlook email client. The problem appears to be focused on that particular email client. Check out this response from Microsoft regarding that error. It may have the answer you need to resolve your error.

      If you have any further questions or comments, please let us know.

      Arnel C.

  • I have a small business and recently moving my host email through to outlook 2007, i added the account and had a message:  Send test e-mail message: Outlook cannot connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).

    Funny I can receive emails but cannot send – I changed the port from 25 to 2525 but there must be something incorrect.  


    Any help? 

  • Thank You So much Sir!!


    I was also facing problem of sending an email via outlook but by the help your arcticle i have found my sloution and this was very helpful to me.

  • With a change over at work of broadband, I successfully changed my SMPT settings and all is fine for sending and receiving emails from my work computer but now I can no longer send emails from my phone or home computer any advice would be most helpful

    • Hello David,

      The change of your work computer settings for email will have no effect on other devices unless they’re synched to use the same settings some how. You need to check the settings being used with your devices . They should be up-to-date and using the same settings as your work computer is using to connect to the mail server. If you are an InMotion Hosting customer, you can find your email settings here.

      If you have any further questions or comments, please let us know.

  • Hi,

    I am not able to setup Outlook for my Gmail. I want sent folder also, so I am using IMAP as it was working with POP, but not getting sent items.

    With IMAP, incoming message working successfully, but when sending I am getting an error message that says, “Send test e-mail message: Cannot find the e-mail server. Verify the server information in your account properties.”

    I have tried using SSL with port 465 and TSL with port 587.

    Please assist me.

  • gone through their trouble shooting steps a couple times.

    Could my router be blocking the connection or could it be a port?

    It’s a TWC/Spectrum account?

    Our IT pro is confused too…

    • It seems like your router could possibly be part of the problem, but really we are not authoritative regarding Microsoft’s products. I would recommend contacting Microsoft directly, and perhaps also your Internet Service Provider( ISP ).

  • For two days I have had a propblem with sending emails. From some recipient adresses I get “Mail delivery failed” messages as below:

    This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: host [] SMTP error from remote mail server after RCPT TO:<>: 550 5.7.0 Host is not allowed to send mail for ‘’ : Reason: mechanism


    Reporting-MTA: dns; Action: failed Final-Recipient: rfc822; Status: 5.0.0 Remote-MTA: dns; Diagnostic-Code: smtp; 550 5.7.0 Host is not allowed to send mail for ‘’ : Reason: mechanism

    Some recipients are ok; some are rejected. Doesn’t matter if I sent using SSL or non-SSL SMTP.

  • Hello Sir,

    appreciate it very much.

  • Hello,

    I have an iPad Pro and an iPhone that pretty much run my business.  Every since the IOS 10 came out both of my devices will no longer accept the security certificate for the emails.  Now I can only receive emails, nothing seems to be accepted when I try and send an email.  Is there a solution for this ? IOS devices run my contracting business and must be able to work.



    • The steps here should allow devices to work normally. If they are still presenting issues, you may want to contact your Apple support to see if there is a specific setting on the devices that needs to be set.

  • Had the same problem, went to inmotion support (nothing helped that they offered) and finally found the answer with a bit of googling the name of my router and web service:

    Answer: Check your router! My home webservice (T-Online) has the router (that they give customers) set up so that the only SMTP traffice is through their SMTP….reason to limit/block spam mail….however one can go into the router admin section and change the setting (they allow it) and TA-DAH! the email goes through immediately!

    Check your router.

  • i have facing problem in seding email, i can send from webmail but cannot send from outlook 2013. it was working good till yesterday. my setting is pop3. outgoing server require autehntion(use same settings as my incoming mail) outgoing port 587(since day 1). i have checked switching between port 25 and 587 also switched switching sending email authenticaiton checked and unchecked with both ports(25 and 587) incoming is ok . sending from webmail is ok. please suggest solution.

    • If you have checked your ports and toggled the authentication, then you can rule those out most likely. I would try and re-enter all your settings to see if that helps.

  • It is effecting all IOS apps that do mail, both iOS native Mail app and any third party apps. Some cannont authenticate, others cannot send email which others can recieve. It seems like there is some issue with the latest update to iOS 10 (which is when the issues began) and authentication to your servers via iPhones. Wasn’t sure if others were having this issue. 


  • Hello,

    All of a sudden i cannot set up my email on any of my IOS apps. The ones it was previously set up on now won’t send the emails. I have checked my settings to make sure they are correct, and they are as instructed above. Username is full email address, pass is verified correct (can log into webmail) incoming is port 993 and server is Outgoing is 465 and is the same as above. Please advise as I am unable to send any emails at this time on my phone, which is not acceptable for my business and if not resolved may result in us having to get hosting elsewhere.

    • Daniel, I’m sorry to hear that you’re having this issue, but I’m happy to help! Are you also making sure that you have set SMTP Authentication to ‘required’? When did this issue begin? As this is a public forum and sensitive information should not be shared here, have you contacted our Live Support team for account specific assistance with this issue? When did this issue first begin? Have your devices updated recently? Are you using the IOS mail application, or a 3rd party one? What version is the mail application itself?

  • Sometimes we can send emails and sometimes we can’t. Can received them

    Port 25 is open on mac.’

    Our settings are absolutely correct as have done online chat with 2 tech support to confirm this.


    Online doctor says can’t connect to SMTP inmotion host server.


    How can we send emails?

    • We are happy to help you troubleshoot further but will need some additional information.

      Are you getting any errors, or bounced returned emails? Can you provide them?

      Are you able to send email from Webmail? Since this is just an email client (like mac mail, outlook, etc.) it will confirm if the server’s mail services are functional.

      When this happens are you on the same network/location, or are you connecting to via networks?

      Port 25 may be open on your mac, but it depends on your network. For example, many ISP’s block ports on their networks. Often public wifi, or even college/university networks block ports as well.

      I recommend reviewing your mail logs for additional clues since it provides specific evidence and record or your connection attempts.

      Thank you,

  • As of Sept 8 a.m i have been unable to send emails from my personal email account.

    The message reads that I reached my limit.

    I only send emails one at a time and send average of 20 per week – if that.

    This has never happened to me before.

    I did check at 1 a.m. on Sept 9 and it worked again for one test email. I then went to bed – but then at 9 a.m. I was blocked again.

    It also looks like my email is being used by ‘someone’ sending out BIRTHDAY and COUSIN DAY greetings. These messages hit my email as SPAM and undeliverable.

    I am using my gmail via explorer non-chrome and on ios iphone 5s.

    Thank you

    • In your email headers indicate your email is being delivered to the recipient server, but is being refused delivery because the IP is blacklisted with SpamHaus.

      I recommend contacting your email host so they can request delisting from SpamHaus.

      Thank you,

  • We are getting outgoing email flagged as Spam. We had this before and requiring SMTP authentication took care of the problem at the time. Now it seems to happen only on a second or third generation reply. New emails go through fine. Any thoughts on how to remedy this? Thanks!

  • Hello dears ,

    • Hello Dyari,

      Sorry for the problem with your email. MS Exchange server is a mail server that is supported by your network. We do not provide support for that type of mail server or service. Your best avenue of support is to contact your local IT network people to see why your mail account is not accessible.

      If you have any further questions or comments, please let us know.

  • For a month I had the same problem.  I don’t know if this will work but my sent box was so full it wouldn’t let me send anything out.  I removed all the sent mail in the folder and it worked after that and I haven’t had any problems since.

    • If you have already tried troubleshooting with different email settings and different email client configuration and checked with your ISP then you can also check your mail logs to see if you have get more specific information about the errors are coming from.

    Background:  For 2 years, I had no issues using MS Outlook 2013 to send/receive e-mail using my URL e-mail server.  Upon returning home from vacation on 7 May 16, I was able to receive e-mail using MS Outlook 2013, but was unable to send e-mail.  Upon checking the Outlook Account Settings, I found out that I was also unable to send a Test e-mail using the settings that I had been using successfully for the last two years.  These settings were:  Account Type:POP3; Incoming Mail Server –; Outgoing Mail Server:; Logon Information: My Login and Password from my account; Under More Settings: My Incoming POP3 Server = 110, Outgoing Server = 587.  NO encryption boxes checked whatsoever on ANY of the Tabs.

    After fault isolating the problem with, they duplicated my Outlook parameters on their MS Outlook 2013 machine (using my Login/Password information that I provided them).  They were able to send/receive e-mail without issue.  This action prompted me to think that something had changed with (Cox made a change effective 1 May 2016).

    Solution: I made the following changes to my MS Outlook Account Settings and now everything works fine again.  Changed Outgoing Mail Server (SMTP) to: (I chose this SMTP address since I subscribe to Cox out of Alexandria, VA…your choice may be different!); Under More Settings, click the 2nd TAB (Outgoing Server), click the box near the top “My Outgoing Server Requires SMTP Authentication”; Click the Radio Button that says, “Log On Using” and type in your UserName and Password to your account.  Be sure to check the box “Remember Password”.  Attempt to test the account settings and you should get two Green check marks.  Finish the process to Save Your Changes and then attempt to send an e-mail from MS Outlook 2013 to ensure everything works.

    I hope this info helps,


  • I can receive email on my mac but its just stoppped sending.  i phone still working fine.  I connected to wifi at Melbourne airport recently thats the only thing thats changed.  If I chnge my password with hotmail would it muck up my phone too or is the problem with microsoft for blocking something because recent activity has changed


    • Hello Sandy,

      Thank you for contacting us. Often, public networks (such as airport wifi) block ports. I recommend trying the two solutions above, instead of changing your password.

      Thank you,

  • My Office and I thank you all so much. This week would have been three weeks that we’ve not been able to send an email using Outlook. I can’t remember how I got here but this worked like a charm. All fixed now and we also now see why we had the problem to begin with (port 25).

    • Hello,

      What type of phone are you trying to access your mail on? Are you wanting to use IMAP or POP3?

  • I have recently experienced this error when trying to reply or send email:

    “Login to server failed.  We have been on your server for approximately two months and have no issues whatsoever in sending or replying to email, until yesterday.  There’s no reason why settings that worked in Mozilla Thunderbird have now simply stopped working.  I perused your suggestions and double checked incoming/outgoing server settings, (which have worked with no problem previously)




    • Hello Sandeep,

      Sorry for the problem with your email. As per the error, the authentication of the user is being questioned at the client. You would need to check that users’s credentials at the client or server in order to correct it. The error indicates that the user is coming from a Yahoo account. If we are to investigate it further, you would need to provide account information as well as the settings you’re using for your mail client.

      If you have any further questions or comments, please let us know.

    • Hello Ron,

      If you are on a Reseller server, those settings are not correct. They should be set to for the reseller account. The reseller name servers are not the same as the InMotion Hosting servers.

      I hope this helps to answer your question, please let us know if you require any further assistance.

    • 1. Go to Account Settings (Tools > Accounts)
      2. Click on the “Mail” tab
      3. Highlight your GreenNet email account, and then click on “Properties”
      4. On the “Servers” tab, check that you are using GreenNet’s SMTP server. Outgoing mail (SMTP) should read “”
      5. Make sure there is a tick in “My server requires authentication” (the “Settings” should be “same settings as incoming”).
      6. Next, click on the Advanced tab, under ‘Server Port Numbers’ change the Outgoing mail server port from 25 to 2525 (or vice versa, depending on which one you have there already. You could also try 465 with encryption).
      7. Save your changes and try sending email again.

    I think my account is been hacked.

    • Hello Rayna,

      Sorry for the problems with the email/email address. Have you tried clearing the outbound emails that are stuck with this address and just sending a test message? It’s possible that if one message is queued in the outbound and being repeatedly blocked. The message could possibly be flagged for spam and then not allowed for outbound traffic. We can not verify this for you unless you’re an InMotion customer and you provide us the email address in question. Blocking emails by address is not something that is typically done on our servers. If you want to handle the issue privately, please submit a verified support ticket along with the necessary account and email information so that they can look into it for you.

      If you have any further questions or comments, please let us know.

  • Hi There, I was hoping this site would fix my problem, but my problem is slightly differrent. I’m on Miscrosoft Entourage for Mac, and all of a sudden there is one contact in my address book where I can no longer send or receive emails. I can sned and receive on my IPad, so I assume there is some sort of filter that has been allocated to the email address. I have tried tp shceck the Properties assigned to the contact, but I can’t fix the problem. Can anyone help please?

    • Hello Rayna,

      Are you by chance getting any bounce back errors? Have you tried removing the contact from your address book and re-adding it? You may need to do the same with your mac mail account itself.

  • Hi,

    I can receive E-mails but I’m unable to send out any emails..

    It says that the .pst file has errors… we still couldn’t find ways to fix it.

    • Hello Audrey,

      Thank you for contacting us. I first recommend double-checking your SMTP settings for misspellings, you can view your specific email settings in cPanel at anny time.

      Also, as a test try rotating your settings. For example, if you are using the non-SSL setttings for SMTP, try the SSL settings instead (and vice versa).

      Thank you,

    • I would suggest checking your anti-virus and firewall settings. Turn off any anti-virus software and attempt to send. If that doesn’t work disable your firewall and see if you can send then.

    Thank you

    • Hello rajesh,

      You will want to contact the owner of the list you are on. Sometimes it is a blacklist service, other times it is simply the owner of the receiving server itself. Contact them and ask how to get your email IP removed from the list so you can once again send emails.

  • I email our members.  I created a email account.  I send the email to that email address and BCC to the member’s personal email addresses.  Recently, I get a pop-up error window stating that it cannot be sent.  It only allows about 50 emails to be sent at one time.  So, since we have over 150 members I have to send the same email 6 or 7 times to get through the list of email addresses.

    Also, when I send an email to the I get this message returned.  However, the email does deliver the email addresses.

    • Hello Randy,

      Sorry for the problem with sending emails. The problem has to do with a an established limit for sending emails (50). There is also a 250 mail per hour limit on all account. If you are continually sending a newsletter or message to multiple people that number in the hundreds, then I highly recommend using a service called MailChimp. This will not only allow you to send to your member list in one shot, it also is highly customizable and does not affect your hosting account.

      I hope this helps to answer your question, please let us know if you require any further assistance.

  • I am using Outlook for MAC and just updated to 15.4.2 a few days ago and since then, I cannot send emails from Outlook. I am receiving them fine and can get emails on my exchnage server through the server company (Metisentry) and they do not believe the issue is on their end. The outgoing port was 25 – I hvae also tried 587 and 465, both with and without SSL. None of these options allows me to send email. 


  • Hi! Thank you for this article!

    My issue was this:

    I’ve been using Microsoft Outlook 2010 at work with 4x E-mail Accounts with no hassles for several years. All of a sudden, an error message popped up saying Outlook could not connect to my incoming POP server, and to check with my ISP or administrator? What the hell!?

    I double-checked the passwords, they were correct. Logged in via webmail – All good. I couldn’t work out why Outlook suddenly decided not to work? I could send e-mails, but not receive anything.

    Anyway, my solution was as simple as changing the port from 25 to 587.

    I don’t know whether it was blocked by my ISP, or my web host, or my computer! But either way, it worked.

    • Hello Nick,

      Thanks for the comment. Yes, port 25 is often heavily used by spammers, so many ISP’s have started to block it. If you have any further questions or comments, please let us know.

    • Hello Betty,

      If your emails are not being delivered, they usually get bounced back along with some details. The details contain a reason it was returned. If you have one of those we are happy to look. If you are a customer you may want to forward that to our Live Support team so they can assist you since you do not want to post it here in public.

  • I have Outlook 365 set to use my gmail account with IMAP.  It sends and receives emails.  However the “sent” folder in outlook does not sync or update.  When I first installed it recently it downloaded “sent” items from over a year ago.  It never downloaded anything more recent and it continues to not download any sent items.  If I open my “Sent Messages” folder it appears that I have not sent a message for over a year.  However, if I log onto gmail through my browser the sent items are there in the proper place.  Any ideas?

    • Hello Roxanne,

      Thank you for contacting us today. We are happy to help, but will need some additional information. Have you subscribed to your INBOX in Outlook?

      This allows you to view the folders stored on our servers. Although, Gmail’s settings may differ.

      If you have any further questions, feel free to post them below.

      Thank you,

      Thank you,

    • Hello pbear12,

      Thank you for the information. Also, we can Auto Archive email for you.

      This can really help IMAP users, since every time you connect it has to sync & list every single email.

      Thank you,

  • After not being able to send out mail for over a month I did a lot of research and found a solution that worked for me.  Move all of your sent mail to another folder or delete the messages.   Make sure your outgoing mail is set to the default settings.  Your sent mail will only hold a limited amount of GB.

  • I can’t send emails via Outlook on my Mac – it keeps saying error code 150.

    My outgoing mail ports are fine – i can send via webmail but not via my iPhone or Outlook. Any ideas??

    • Hello Jared,

      Per Microsoft’s forum, the error 150 that you’re seeing is an “unknown error”. This doesn’t help much, but the discussion on the forum was that people were able to switch the outgoing port and it would work. I don’t know if you are an InMotion customer or not, but the information on this article is used to identify the email settings. Since your problem is with Outgoing mail, the settings are a likely culprit. If you’re not using SSL settings, then switch to them. If you are using SSL, then turn SSL off and make sure that your outgoing port is set to 587.

      If you continue to have the problem, please provide us the email settings that you’re using, the version of Outlook and Mac iOS that you’re using. We can then investigate the issue in more depth.

  • Dear John-Paul,

    e-mail is hosted by I have company so it goes thru my site. Yes I use mozilla thunderbird. like when I send an e-mail to any mail hotmail,gmail only half of my text is shown. I don’t use mozilla firefox.


    Thanks in advance,



  • Hello, My problem is that when I send an email, the receiver only gets to see half of the text. so my email is 200 words long, once the mail is send from mozilla, only 100 words show up. do you people know what the problem is?

    • Hello safeer,

      Thank you for contacting us. We are happy to help, but will need some additional information. Who is hosting your email? For example, is it hosted on our servers, gmail, hotmail, etc.

      Are you using Mozilla Firefox to access email on webmail?

      Are you using Mozilla Thunderbird to send emails?

      Thank you,

  • Hi Jean-Paul,

    Comcast pointed me to the right direction , that was something with Out data files (.pst), I did removed all accounts & data files, pointed to old “.pst”, recreated accounts and magically it start working. Thank You all for the help,

  • Hi Scott,

    Yes, I did try same settings as Outlook2003, as well as Comcast preferred setting for Outlook-07/10/13, same results. Maybe Comcast doesn’t support Out365 at all ?!

    Thak You for Your help,


    • Hello Kestas,

      Thank you for your question. I recommend contacting Comcast, so they can troubleshoot the problem in real-time.

      For example, our Live Support team can monitor the server logs and see if you are connecting to the server or not.

      Thank you,

  • Hi All,

    My problem: Outlook-365 can’t send email using server.

    Test messages – OK. Receive – OK.

    When trying to send – error 0x8004010F An object can’t be found.

    I tried No security, SSL:465, TLS:587. Same result.

    Outlook-2003 works just fine.

    Any ideas, Cheer kes

    • Hello Kes,

      If your Outlook 2003 is working, then you want to make sure the Outlook 365 has absolutely the same settings. If they do, you will want to check with Outlook 365 support for help because the only thing you should need are the proper settings for it to work properly.

      Kindest Regards,

  • Thanks Jeff. Helped me a lot. Before I can receive but can’t send emails. Now, I can send emails from my mac. Thanks guys!


  • Thanks Arn, yes I have all those settings.  (Use SSL of course.)  It may be my unfamilairity with T-bird:  I’ve got the micro-metrics ones working fine now — but the snowtao ones are still choking.

    Okay, I deleted one of the two addresses that appear in the left-hand pane in T-bird and recreated it, using manual config.

    Incoming: POP3 port 995, SSL

    Outgoing:  SMTP port 465 SSL

    Tested and retested, and it keeps saying the “config couldn’t be verified and asking if the username or password is wrong.”  The ID and pword work in webmail.

    But:  “Sending of password for user did not succeed. Mail server responded: Login failed.”

    (In Account Settings:  I’m now up to ELEVEN (!) options in the dropdown for “Outgoing Server (SMTP)”  — HOW do I delete any of those?)

  • Hey Scott, this is the error message: 

    Sending of password for user ****** did not succeed. Mail server responded: Login failed.


    Sending of password for user ***** did not succeed. Mail server responded: Login failed.

    I know the user IDs and passwords are correct because I can take them directly into webmail at IMH and they work.  (And I’ve tried the Comcast password, and the snowtao passords and the IMH password…)

    In Account Settings — for the Outgoing Server / stmp, I now have TEN of them — one for each email address, plus one I’ve called Comcast Relay (which is merely a repeat of the Comcast email address that I only use for the Relay).  The “Default” server (in “Use Default Server” is set-up as the “Relay Comcast – (Default)” one.

    Ideally, there would be two? Three?  The personal domain ( and the biz one (  And maybe or maybe not? The Comcast Relay one?  I’m guessing they all were created (cause I don’t remember doing so) when T-bird pulled my emails addresses and folders over from Eudora?)

    Weirdly, the biz address pulls incoming emails (and seemingly answers them as well). It shows the server name as “” — and its outgoing server (with correct secure number) is: –

    However, the various addresses show the server name(s) as “” — but its outgoing server is (each) “ —”.  And I cannot find anywhere to edit those?

    Thanks!  (Sorry it’s so long — want to make sure I’m providing enough info!)


    p.s., and just to complicate matters — I have three accounts showing in the left-hand pane in T-bird:  two personal addresses and the biz (well, one of two) address(es) showing. The others?  Appear IN Account Settings — but I cannot find anywhere (and I have searched the web!!) that tells me how to get the others to show in the left-hand pan eo fht emaion T-bird view… So I cannot get them to check for mail — but if I try to create a new Account (?) in the left-hand pane, it tells me there is already an account named that… (“Well, yes, but I want to SEE that account, you know?”)

    • Elenor,

      Sorry for the continued problems with Thunderbird. If you are using our servers for outgoing messages, then the settings should be based on the our outgoing settings. It’s not immediately apparent what you are using for your email settings, but they should look like this:

      NON-SSL Settings:
      user name=
      email address password
      Outgoing email server port = 587
      Security = NONE

      SSL settings (can also be: example:
      user name=
      email address password
      Outgoing email server port = 465
      Security =SSL

      You can also go here to find your email settings if you’re not sure: How to find your Email Settings.

      Hopefully, this clears up the issue. If you’re still having problems after making sure your settings match up, then please let us know.

    • I cannot find how to use (my newly set-up) T-bird to SEND msgs through Comcast (my ISP), from either of my two InMotion domains ( and In Eudora, I have the Comcast email set-up as a relay account, and both domains are able to send and receive emails. T-bird imported all my Eudora mailboxes and personalities, and I have gone through each getting them correct — but can’t send or receive?

    • Hello Elenor,

      If Eudora is working with our accounts via ComCast, then the same settings would be used for Thunderbird. All email clients would use the same information as it is simply connection information it is looking for. Is there a specific message you are getting when it fails?

  • All at once, my email box, where I would write my message, appears to be “dimmed” and it will not let me type anything into it.  This also happened on my laptop.  I am totally confused, we had a power outage last night, but my computer was not up and running when it happened, it took nearly an hour for it to restart.  I am with Centurylink and Windows 8 on my PC, the laptop is a Dell, windows 7.  I am not a computer genius by any means.  Help…what good is a computer if you can’t send a message?

      What email client are you using? Are you able to log into your webmail at all? Is this specific to a single email account? Does it work from other networks such as a phone carrier? We can help with anything server side, but just need to know more information to understand if this is server side or on your side.

      Kindest Regards,

    • Hello Marry,

      This seems to be a common problem with Mac mail users. In the official Microsoft forums, they advised to make sure nothing is stuck in the Out box.

      If you have any further questions, feel free to post them below.
      Thank you,

    • Hello sivamalepati,

      Thank you for the follow up information. I recommend reviewing the email logs to see where the emails are being stopped. If you are hosted with us, Live Support can help you review the email logs.

      For example, you can see in the logs if they are being delivered to the recipient server, or being rejected before that.

      Thank you,

    • we are not hosted with you, still you can help us? i checked with our mail server people, they say windows live mail has problems, but i don’t find any issues, am able to receive mails and able to send, unfortunately we are not able to trace out where the mails are missing. can you please advise any modifications/help for me work accordingly. regards-sivaprasad

    • Hello,

      We are happy to help, but will need some additional information. Have you tried any of the steps described above? Have you checked that your email settings are correct and without typos?

      Have you tried restarting Windows Live Mail?

      Did you recreate your email account in Live Mail?

      Can you confirm there is nothing stuck in the outgoing box?

      Thank you,

    • hi,
      there is nothing struck in outbox, idid not recreate mail account, i did restart windows live mail several time since few days, nothing is happening. e- mail settings are correct, iam able to receive and send, the out going mails are not reaching the end user.

    • Hello sivamalepati,

      If you are not seeing anything still in the outbox, then you may want to contact the owner of the mailserver to have them take a look and see if the email left the server and got a response from the recipient’s server. If there is an issue, then it may have an error in the server log that they can adjust.

      Kindest Regards,

  • Hi,

    I’m facing a techinical issue in outlook 2010, while i send the mails from my ID but where the receiver end it is appearing with different name.

    Is there a solution to sort the issue.

    • Hello,

      Please explain in a little more detail what is happening. Does this happen to only one email address or multiple? Did the behavior occur recently or has it always done so? Does this only occur when sending via Outlook as opposed to webmail? Are you one of our customers so we may be able to take a look in the server to see what is going on?

      Kindest Regards,

    • I live in Hong Kong and since I updated to 10.9.4 on my Mac I have not been able to send mail. Port 25 is not blocked. I have tried using a VPN as well to ensure it is not my ISP. Mail can send from Webmail, but from Apple Mail with SSL or no SSL, designating specific ports or selecting Default Ports I can not connect to the SMTP server.

    • Hello,

      The mac and iphone should use the same settings. Also, test to ensure the iphone is sending from the same network. Barring any network issues, the settings are the only thing needed to connect.

      Kindest Regards,
      Scott M

    • Hello Michael,

      You will want to check all the settings to ensure they are correct. If you are connecting via the webmail and not the mac, then it is something on the mac side. Just check to ensure the update did not make any changes to your settings so that they are all as they were prior to the update.

      Kindest Regards,
      Scott M

    • The article states up near the top that the servers for SSL are, I get an error if I use that. cPanel (within the hosting) guidance states it is which does work. Your examples show incoming IMAP/POP settings, but the port shown is 993 which is just for IMAP, so these are misleading. I have also seen elsewhere in your help pages another setting for the server which was different again. In my case, I have recently moved to InMotionhosting, along with 40 websites and have been trying to use secure settings for email. I am based in the UK, with British Telecom as my ISP. I have spent around 4 hours trying to set a secure POP3 email account up and running using the information from your cPanel and from the various help items on your website and over 30 minutes chatting with technical support who could not help either. However I have come across a solution. I get a timeout if I try to use port 465 for SMTP on a Pop3 account. This port is not blocked from within my system, but I suppose it might be blocked by BT (ISP). It still times out if I am not using any security. However I have found that Port 587 and selecting TLS as the security type does work with the (My POP3 incoming server is set up on SSL and using port 995.)
      I hope that helps. The thread here is particularly long, so a lot of people are finding difficulty here.

  • My Outlook 2010 quit connecting to the server yesterday at 11am.  I’ve restarted outlook several times.  restarted my computer. but it won’t connect to my server.  I’ve called my email provider & they are not having any issues.

    I have my incoming IMAP at 993

    Outgoing SMTP 465 both with SSL encrypted.

    Everyone keeps telling me it’s not an issue on their end but still I don’t have emails.  i can go into web mail & see that I have 100s of them waiting for me.


    • Hello SANDY,

      Thank you for your question. There are several things you can check.

      Since ports are often blocked, have you tried the alternate email settings using the following ports?
      IMAP: 143 (instead of 993)
      SMTP: 587 (instead of 465)

      You can view all your email settings in cPanel at any time.

      You an also test if your email ports are open using Telnet.

      If your email is hosted on our servers, it may be easier to contact Live Tech Support so they can review the email logs in real-time (while you are attempting to connect).

      If you have any further questions, feel free to post them below.
      Thank you,

    • Hello swapnil,

      Thank you for your question. The important part of this returned message is as follows:

      Unfortunately, messages from weren't sent. Please contact your Internet service provider since part of their network is on our block list. You can also refer your provider to

      This means your mail IP is most likely blacklisted

      I recommend contacting the mail host for and advising them of this blacklisting.

      Also, you may have to email this person (swapnil_p**** from a separate email address, and requesting that they whitelist you.

      In the future, we have a Bounceback email tool that can help determine the cause behind returned emails.

  • I have cox for my email and noticing that some emails that people send me on cox I can get on my cell or on gmail (I have them going there currently since I am having this problem) but they are not coming in on my entourage. Like I stated only some emails this is happening with.  What do I do to fix this?

    • Hello Lisa,

      The first thing to check is make sure that you don’t have multiple devices setup to check your Cox email account that are setup as POP, as the default behavior is to remove new messages from the server and download it locally to the mail client. So if you phone downloaded a new message, and then you check on your desktop in Entourage, that email would only be on your phone and no longer on the server for Entourage to view.

      If certain people are unable to send email to your Cox account, more than likely they are sending from an email server that Cox has blacklisted. We have a guide on why mail servers get blacklisted that reviews why this can happen.

      Unfortunately to get around these types of issues, typically the person sending you an email to your Cox account should receive an email bounce back stating the exact reason why their message wasn’t delivered. If it was because the server they were sending from is on a blacklist, they would want to request a delisting from a blacklist.

      If it’s not due to the sender trying to send their email from a blacklisted server, they should still get an email bounce back, and here are the Cox email error codes they might receive if their message is being blocked for another reason.

      You might need to contact Cox directly for more help, as looking at the Cox Postmaster guidelines, they have published these sending guidelines that some people trying to send to you might not be following.

      What are Cox’s sending limits?
      Cox currently allows up to 5 simultaneous connections per sending IP address, and up to 100 messages per connection. However, regardless of these limits, Cox may throttle your sending ability based on your sender reputation. Cox’s sending limits and policies are subject to change at any time. Cox will update this website when changes are made.

      Please let us know if you had any further questions at all.

      – Jacob
