Encountering a “550 No Such User Here” error when sending an email indicates that the recipient’s mail server cannot locate the specified email address. This issue can have various causes, requiring a distinct troubleshooting approach.
Common Causes of the “550 No Such User Here” Error
- Incorrect Email Address: The recipient’s email address may be misspelled or formatted incorrectly. Even minor errors can prevent successful delivery.
- Non-Existent Email Account: The recipient’s email account might have been deleted or never existed.
- Misconfigured Mail Exchange (MX) Records: If the domain’s MX records are not correctly pointing to the intended mail server, emails may not reach the correct destination.
- Email Routing Issues: Improper email routing settings can cause the server to misdirect emails, leading to delivery failures.
- File Permission Errors: Incorrect file permissions on the mail server can prevent the server from accessing necessary files, resulting in delivery errors.
Steps to Resolve the Error
- Verify the Recipient’s Email Address:
- Ensure the email address is correctly spelled and formatted.
- Confirm with the recipient that the email account is active.
- Check MX Records:
- Use DNS lookup tools to verify that the domain’s MX records point to the correct mail server.
- If discrepancies are found, update the MX records accordingly.
- Review Email Routing Settings:
- In cPanel, navigate to Email Routing and ensure it’s set appropriately:
- Local Mail Exchanger: If the server hosts the recipient’s email.
- Remote Mail Exchanger: If an external server handles the email.
- In cPanel, navigate to Email Routing and ensure it’s set appropriately:
- Inspect File Permissions:
- For cPanel users, incorrect file permissions can cause this error.
- On VPS or Dedicated Servers, run the following command to reset permissions:
fixperms username
Replace “username” with the actual cPanel username.
- Contact the Recipient’s Email Administrator:
- If the issue persists, the recipient’s mail server may have configuration issues.
- Reach out to the recipient or their email administrator for assistance.
Preventive Measures
- Maintain Updated Email Lists: Regularly update your contact lists to remove invalid or inactive email addresses.
- Configure DNS Settings Correctly: Ensure that DNS and MX records are accurately set to point to the correct mail servers.
- Monitor Server Permissions: Regularly check and maintain correct file permissions on your mail server to prevent access issues.
Identifying and addressing the underlying causes can effectively resolve the “550 No Such User Here” error and improve email deliverability.
Kindly assist me I’m too getting this error
Hello Sabarihospitality2022@gmail.com – 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=[209.85.167.52]
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 recommend you check out applicable troubleshooting guide.
Per the link you provided, change smarthost1.slhost.com’s SPF record so that it authorizes mail-wm1-x32b.google.com. You can do this in cPanel Authentication.
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 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.
hello,
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 ?
Rergards
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’ ?
Hello,
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.

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!

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:

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
550 invalid DNS MX or A/AAAA resource record
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.”
