How to Fix the 550 No Such User Here Email Error

One common error you can get when sending email is the “550 No Such User here” error. This error occurs when the sending email is rejected because the username cannot be found or is not accessible by the server. There are several reasons why you would get a “550 No Such User Here” error.

  • Mail file permissions are not readable or are incorrect.
  • The email address was typed incorrectly.
  • MX records are incorrect ( pointing to the wrong server ).
  • Email does not route correctly ( Remote / Local domains ).

This error can go both ways, meaning, people sending to your server may get the error and when you send from your server to another you may get the error. Depending on where the error bounce is generated from will determine what you can do about fixing the error.

If you get “550 No Such User Herebounces sending from your server to another server, you most likely will need to contact the host or email administrator of the server you are emailing to fix it.

If you are getting complaints that people sending to your server are getting this bounce, you can check / change the settings on your servers end. Below are the reasons why the 550 error may occur when you email.

Mail file permissions are not readable or are incorrect

All our servers store email in the “mail” directory of the “home” folder of your cPanel account. If the file permissions are corrupted ( sometimes caused by server moves, back up restorations, or recently uploaded files through FTP, etc.) you will get this error for all your emails. This is a simple fix. You can contact tech support to have the file permissions fixed on your server. On VPS and Dedicated servers, you can run the following from command line:
[root@vps#### ~]$ fixperms userna5

This will reset all your file and folder permissions to folders 755 and files 644 for teh cPanle user userna5. If the email bounce is coming to you when you send to another server and it’s permissions related, the person you are emailing will need to contact their hosting provider to fix the permissions on their end.

The email address was typed incorrectly

550 No Such User Here” Errors can occur when the email address you are sending to is typed incorrectly. In this case, just make sure you have the email address spelled correctly.

MX records are incorrect ( pointing to the wrong server )

If you recently moved your domain to InMotion Hosting and you started receiving these errors, you may have a DNS nameserver or MX record problem. The MX records point your email address to a specific server. If the MX record is pointing your domain to the old hosting company and you removed all your email accounts off that server, when you go to send your email, you will get the “550 No Such User Here” error. You will want to check the following through command line:
[root@vps#### ~]$$ dig example.com mx ; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.10.rc1.el6_3.6 <<>> example.com mx ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 8149 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 3 ;; QUESTION SECTION: ;example.com.                 IN      MX ;; ANSWER SECTION: example.com.          14400   IN      MX      0 example.com. ;; AUTHORITY SECTION: example.com.          54747   IN      NS      ns2.inmotionhosting.com. example.com.          54747   IN      NS      ns1.inmotionhosting.com. ;; ADDITIONAL SECTION: example.com.          13322   IN      A       66.117.4.177 ns1.inmotionhosting.com. 11994   IN      A       74.124.210.242 ns2.inmotionhosting.com. 11994  IN      A       70.39.150.2

The example above shows that domain example.com points to the ns1.inmotionhosting.com and ns2.inmotionhosting.com nameservers and that the MX routes to the InMotion Hosting server.

Make sure your nameservers are pointing to us. If your nameservers do not point to our server, then your domain will not route to our server unless you make special DNS changes at the host the nameservers point to.

Make sure the MX records for your domain are sending to the correct server. If your domain does point to the correct server, check the MX records to see if the email is pointing to the correct server in the cPanel MX entry.

If your nameservers and DNS are correct, then you will need to check the email routing. If the bounce message is from you sending to another server, then the person receiving the email will need to check with their email provider for a resolution.

Email does not route correctly ( Remote / Local domains )

In the case that you are receiving bounces to a specific email address, you will need to find the MX records and the nameservers for the receiving domains DNS. Run the following DIG in the Linux command line to find the Receiving servers nameservers.

To find out if your domain is on the receiving email servers DNS nameserver, you can DIG the domain for their nameservers. Once you get the nameservers for the receiving domain, you can check the DNS for your domain using their nameservers. Below will explain in detail.

Dig the receiving server domain to find the nameservers:

Below shows what a DNS MX record DIG looks like for notexample.com.

[root@vps#### ~]$ dig notexample.com mx ; <<>> DIG 9.8.2rc1-RedHat-9.8.2-0.10.rc1.el6_3.6 <<>> notexample.com ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 8587 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 2 ;; QUESTION SECTION: ;notexample.com.                 IN      A ;; ANSWER SECTION: notexample.com.          14400   IN      MX      0 notexample.com. ;; AUTHORITY SECTION: notexample.com.          85619   IN      NS      ns1.somenameserver.com. notexample.com.          85619   IN      NS      ns2.somenameserver.com. ;; ADDITIONAL SECTION: notexample.com.          13322   IN      A       25.22.80.62 ns2.somenameserver.com. 18391 IN     A       25.22.80.62 ns1.somenameserver.com. 18391 IN     A       25.22.67.43 ;; Query time: 1 msec ;; SERVER: 74.124.198.200#53(74.124.198.200) ;; WHEN: Thu Mar  7 06:08:06 2013 ;; MSG SIZE  rcvd: 136

The results of this DIG shows that the nameservers for the receiving server notexample.com has the nameservers of ns1.somenameserver.com and ns2.somenameserver.com. The MX record points to notexample.com which has an IP that points to the server the nameservers are on. Next you can check your domain in the receiving server nameservers.

Checking if your domain is in another servers DNS:

Now that you have the receiving server nameservers for the notexample.com domain, you can DIG the DNS records at the receiving servers end to see if your domain is in their DNS nameserver. The following is an example of the DIG command in shell that will look up example.com on the notexample.com server.

dig @ns1.somenameserver.org example.com ; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.10.rc1.el6_3.6 <<>> @ns1.somenameserver.org example.com ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 11023 ;; flags: qr aa rd; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 2 ;; WARNING: recursion requested but not available ;; QUESTION SECTION: ;example.com.            IN      A ;; ANSWER SECTION: example.com.     14400   IN      A       70.39.251.58 ;; AUTHORITY SECTION: example.com.     86400   IN      NS      ns2.somenameserver.org. example.com.     86400   IN      NS      ns1.somenameserver.org. ;; ADDITIONAL SECTION: ns1.somenameserver.org. 14400 IN      A       70.39.251.58 ns2.somenameserver.org. 14400 IN      A       70.39.251.58 ;; Query time: 66 msec ;; SERVER: 70.39.251.58#53(70.39.251.58) ;; WHEN: Fri Mar  8 06:16:18 2013 ;; MSG SIZE  rcvd: 140

The previous response shows that example.com is in the DNS on the notexample.com server. This means that the emails sent to notexample.com are seeing example.com in their DNS, looking for the email address on the notexample.com server, and rejecting it because there is no email address on the server.

To fix this, you will need to contact the hosting company or the domain owner that you are sending to, telling them that your emails cannot go through to their server because your domain is in their DNS. They will ned to “Kill the DNS, change the routing to remote on the receiving server, or remove your domain from their DNS nameserver.

If your domain is not in their DNS nameserver:

If example.com was NOT found in the nameserver on the receiving server you will get the following not found response.

dig @ns1.inmotionhosting.com google.com ; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.10.rc1.el6_3.6 <<>> @ns1.inmotionhosting.com google.com ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 63529 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;google.com.                    IN      A ;; Query time: 0 msec ;; SERVER: 74.124.210.242#53(74.124.210.242) ;; WHEN: Fri Mar  8 06:20:03 2013 ;; MSG SIZE  rcvd: 28

In this case, you can try checking your email routing. If you are sending from your server with us, you will need to set the email routing to local in your MX entry of your cPanel. If you are using a 3rd party application like Google APPs, you will need the routing set to remote.

If this does not fix the problem, then you will want to contact tech support to find out if there is a routing issue with your DNS.

Thoughts on “How to Fix the 550 No Such User Here Email Error

  • I got this email bounceback with strange message and didn’t know who I should contact. I have the report. Should I sent it somewhere?

  • Adding to my comment above, another solution is to just add wordpress@domain.com as a forwarder in cPanel. Doesn’t matter where the email forwards to, or the fact that there is no actual mailbox—just the existence of the forwarder seems to resolve the issue.

    • Hello Robert,

      In order to create a forwarder, the basic mail address configuration is created on the server. The actual email folder structure that holds saved emails for that address is NOT required and can be removed so that any email sent to the forwarder ONLY goes to the address designated by the forwarder. If the mail folder is kept, then a copy of the email is saved at that address. Also, just to clarify, the handling of email is designated on a domain level. You can set email to be handled locally (under the MX Settings), or it can be set to be handled remotely by another mail server. Fairly often, when domains are moved, the mail service may stay with a remote server, but the setting for mail is mistakenly changed to local. This is a common cause of the “No Such User Here” error, because the local mail server is looking for the user on the local server and it cannot be found. Likewise, if the email service is moved to the local server (or vice versa with settings for a Remote server), but the user is NOT created, then that error will occur. I hope that helps clarify the forwarding behavior and common causes for the “No such user here” error.

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

  • I think there’s a fifth reason one might get a “550 No Such User Here” error. I use Sendgrid (a third party) to handle my WordPress email on my InMotion dedicated server. I had my FROM address set to wordpress@domain.com, and I was trying to send TO info@domain.com (assuming the site is at “domain.com”). If the sending address doesn’t exist, and you are sending to another address on your domain, your email may bounce with the 550 error message. Interestingly, sending FROM info@domain.com to info@domain.com works, even though info@domain.com is a forward-only account (like wordpress@domain.com, info@domain.com also doesn’t exist). So the solution here is to use the same FROM and TO email address.

  • I am getting following error in webmail

    SMTP Error: [550] “This account is suspended from sending out mail [ Envelope From:]

    and I’m not able to send or receive mail , please guide me how to fix that 

    • The account you are trying to send from has been suspended. I suggest you reach out to your host. If you host with us, please contact support.

    what shall i do please ?

    • That error is pretty specific. You need to contact Blue Host to ensure the account (email account more specifically) is actually created on the server.

  • 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:
    
      xyz@xyz.com
      No Such User Here

    Mails are coming in gmail/yahoo/hotmail
    • Sounds like you are being spoofed and someone is sending emails with a return address that is yours. So when the email bounces, the no-such-user-here email goes to you.

  •  

    This is the only failure information I received from a message I sent to a group of addresses.  I cannot ascertain which address is bad.  Is there a method whereby I can pinpoint that information?  I found nothing that hinted at which addressee mailbox was “unavailable.”  (This is not a commercial mailing.)

      The error gives a message of “No Such User Here”. This means that the receiving server is no longer able to recognize the email address you attempted to send a message to. This is not usually anything to do with the sending side, unless the email address has been misspelled.

    • Hello Amelia,

      Sorry you’re having problems with email sending AND receiving. If you’re getting a “domain not found error” and you’re trying to send email from an account with the domain not pointed to that account, or there’s something going on with the domain name itself. In this case, the domain is SUSPENDED according to a WHOIS query. Here is my query result for the headingleyballetschool.co.uk domain:

      whois headingleyballetschool.co.uk

      Registrant’s address:
      The registrant is a non-trading individual who has opted to have their
      address omitted from the WHOIS service.

      Data validation:

  • hi,

    when i send email to 8@dewsoftech.com i get following message

    Google tried to deliver your message, but it was rejected by the server for the recipient domain dewsoftech.com by mx00.1and1.com

    and when other party try to send me email they get

    please let me know who need to fix this and how

    your reply is appreicated.

    • Hello Sameer,

      It does sound like you’re using Google’s service to send email. If so, then your MX records (if controlled at InMotion), should be set to REMOTE. Check out this article on how to make that setting.

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

    • Hello Suresh,

      It appears you are getting this error when trying to send the email to another server. You will want to check out our article aboce, but the most relevant information from that article is below:

      “If you get “550 No Such User Here” bounces sending from your server to another server, you most likely will need to contact the host or email administrator of the server you are emailing to fix it.”

      Did you try the instructions above to fix your error? If so, and you are still getting the error, you may need to contact your hosting company. The dig records are showing your domain is with GoDaddy. You may need to contact them if you are certain you have gone over the instructions and the email address exists on the server.

      Kindest Regards,
      Scott M
