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 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.
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
[[email protected]#### ~]$ 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
MX records are incorrect ( pointing to the wrong server )
[[email protected]#### ~]$$ 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 22.214.171.124 ns1.inmotionhosting.com. 11994 IN A 126.96.36.199 ns2.inmotionhosting.com. 11994 IN A 188.8.131.52
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 )
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.
[[email protected]#### ~]$ 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 184.108.40.206 ns2.somenameserver.com. 18391 IN A 220.127.116.11 ns1.somenameserver.com. 18391 IN A 18.104.22.168 ;; Query time: 1 msec ;; SERVER: 22.214.171.124#53(126.96.36.199) ;; 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 188.8.131.52 ;; 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 184.108.40.206 ns2.somenameserver.org. 14400 IN A 220.127.116.11 ;; Query time: 66 msec ;; SERVER: 18.104.22.168#53(22.214.171.124) ;; 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: 126.96.36.199#53(188.8.131.52) ;; 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”
Kindly assist me I’m too getting this error
Hello [email protected] – Please provide more details on the issue you’re having and we would be happy to help!
My email suddenly stopped receiving emails though I can send from the same email address.
The response from the remote server was:
550 5.2.1 … Addressee unknown, relay=[184.108.40.206]
Any suggestions on how to fix? AT&T is of no help
Please ensure the email address is written correctly and there are no special characters or extra spaces in the To: field.
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?
I advised contacting our Live Support team. They can analyze the message and get more information for you.
Adding to my comment above, another solution is to just add [email protected] 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.
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 [email protected], and I was trying to send TO [email protected] (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 [email protected] to [email protected] works, even though [email protected] is a forward-only account (like [email protected], [email protected] 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:  “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.
im not able to send ior recive emails in my blue host rseller , when i send from gmail to my server i get beliow message
The error that the other server returned was:
550 No Such User Here”
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.
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.)
[Return Code 550] sid: Zbrk1t00526qLEv01 :: Requested action not taken: mailbox unavailable
Is there a list above that says something to the effect of ‘the following email addresses failed’ ?
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.
my Roundcube webmail isnt sending or recieving emails. The error message reads –
STMP error (550) failed to add recipient

Help!! I run a small business and this email is linked to my website, I have no IT tech guy to fix this for me! Any advice is massivly appreciated!
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:
The registrant is a non-trading individual who has opted to have their
address omitted from the WHOIS service.
Nominet was not able to match the registrant’s name and/or address again st a 3rd party source on 07-Oct-2014
Gandi [Tag = GANDI]
Registered on: 26-Sep-2013
Expiry date: 26-Sep-2015
Last updated: 07-Oct-2014
*** This registration has been SUSPENDED. ***
WHOIS lookup made at 14:22:36 30-Oct-2015
As you can see, the registration status indicates the domain is suspended. Use of the domain name for email or other internet functions will not operate until the domain is placed back in good standing with the current domain registrar.
I hope this helps to answer your question, please let us know if you require any further assistance.
when i send email to [email protected] 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
550 invalid DNS MX or A/AAAA resource record
please let me know who need to fix this and how
your reply is appreicated.
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.
