No such user email error



No such user email error

Печать Сообщения почтовых серверов — что они означают?

Если вы получили письмо от Mailer-Daemon с темой «Undelivered Mail Returned to Sender», значит отправленное письмо не было доставлено до одного или нескольких получателей. Причина, по которой исходное письмо не доставлено, указана в конце уведомления на английском языке. Наиболее распространенные причины указаны ниже.

Неправильный адрес получателя

Сообщение об ошибке содержит строчки:
User not found
User unknown
No such user here
Unrouteable address
Invalid mailbox
Mailbox unavailable

Такая ошибка может означать, что вы пытаетесь отправить письмо на несуществующий адрес. Уточните адрес получателя и попробуйте снова.

Пример сообщения об ошибке:
: host mail.example.com[192.0.2.120] said: 550 5.1.1
: Recipient address rejected: User unknown in local
recipient table (in reply to RCPT TO command)

В почтовом ящике адресата нет свободного места

Сообщение об ошибке содержит строчки:
account is full
Quota exceeded
User has exhausted allowed storage space
error writing message: Disk quota exceeded

Размер письма больше, чем ограничение на сервере получателя

На сервере получателя установлено ограничение на максимальный размер письма. Если вы отправляете несколько файлов, попробуйте их отправить в нескольких разных письмах.

Пример:
message size 7520647 exceeds size limit 6000000 of server mail.example.com[192.0.2.120]

Это значит, что было отправлено письмо размером 7,5 мегабайт, а сервер получателя принимает письма размером не более 6 мегабайт.

Сервер получателя не принимает почту

Сообщение об ошибке содержит строчку:
Operation timed out

Сервер получателя не работает. Возможно, вы ошиблись в адресе получателя и письмо отправлялось не на тот сервер. Если адрес был указан правильно, то попробуйте связаться с адресатом, используя другой адрес.

Пример:
: connect to mail.example.com[192.0.2.120]: Operation timed out

How to Fix the 550 No Such User Here Email Error

7 Minutes, 24 Seconds to Read

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

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 )

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.

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.

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.

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.

550: No such user here – How to resolve email error 550 in cPanel/WHM Linux servers

by Visakh S | Aug 7, 2015

550: No such user here is a common error reported by cPanel users who primarily use an external mail server (like a corporate MX) to store their mail.

These include users who are trying to setup a mail forward to an external mail server, those who recently migrated or made changes to their account.

In our experience resolving email errors for customers, we’ve seen that anything from improper file permissions to RFC non-compliance can lead to ‘550: No such user here’ error.

Today, we’ll see the three common causes for email error 550 and how we fix them.

1. Email account doesn’t exist or cannot be detected

When a user tries to send a mail through the server, the sending mail account should be present in the server. In domain migrations that are not done properly, it can happen that the email accounts maybe missing.

The customer would try to connect using the old email username, but the server would return an error as it cannot find a matching account. Such situations can be quickly fixed by creating the relevant email accounts.

In cPanel servers, it is also possible that the mail configuration files have incorrect access permissions due to any updates. This prevents the server from confirming the existence of an account, and results in an error.

Such issues are quickly fixed by correcting the file and folder permissions of the account. If the domain’s entry is missing from the mail config file, that too can end up giving ‘550: No such user here’ error.

In servers that we manage, we maintain a detailed checklist for performing domain migrations and validating the website functions after migration.

We also perform periodic server audits to detect and rectify issues such as inadequate permissions or missing config file entries. These actions help us prevent such email errors.

2. Duplicate sender account in recipient server

At times, we see cases where a user is unable to send mails to domains that belong to his old service provider, or to another server within the same network.

For instance, domainONE.com and domainTWO.com used to be with the same provider. domainONE.com was migrated to a new server, but is now unable to send mails to domainTWO.com.

This happens because the name servers of domainTWO.com maybe still having entries of domainONE.com due to improper migration or other mistakes.

In such situations, we contact the recipient server’s administrators and get the phantom account deleted from their servers. In case the recipient server is in our network, the duplicate account is deleted from that server.

At Bobcares, we prevent such errors by conducting periodic server audit tasks, which include detecting and deleting invalid accounts from the servers.

3. Misconfigured mail exchanger

Some domains would have external mail servers like Google Apps, but webmasters may not have enabled remote MX routing for those domains.

To confirm this, we check the MX of the domain, and if it is not pointing to us, we enable “Remote Mail Exchanger” for the domain’s ‘Email Routing’.

550 error is one of the common mail issues reported by cPanel users. Bobcares helps cPanel webmasters quickly resolve email errors, thereby minimizing business downtime.

Email error 553

2 Minutes, 43 Seconds to Read

A 553 email error is normally related to SMTP authentication not being used. Most mail servers require that you authenticate with a valid user on that system, before you’re allowed to relay a remote message out. However some mail administrators will also using the 553 error if a user doesn’t exist or for various other reasons as well.

You should receive a bounce-back message from the server with a variation of email error 553 in the subject, and the body should contain your original message that you attempted to deliver.

Troubleshooting the Email Error 553

Example bounce-back message

Common variations of the 553 email error

  • 553 5.7.1 Not an open relay, so get lost
  • 553 Invalid user.
  • 553 message blocked, you are not authorized to send mail, authentication is required.
  • 553 Null Sender is not allowed.
  • 553 5.1.1 sorry, no mailbox here by that name.
  • 553 #5.1.8 Domain of sender address does not exist
  • 553 5.3.0 … Address does not exist
  • 553 5.3.0 … No such user
  • 553 5.3.0 … No such user here
  • 553 5.3.0 … User unknown, not local address
  • 553-Message filtered. Please see the FAQs section on spamn

  • 553 RemoteDomain.com does not accept mail sent to recip[email protected]
  • 553 sorry, no mail-box here by that name. (#5.1.1)
  • 553 sorry, no mailbox here by that name (#5.1.1)
  • 553 sorry, rcpt user invalid (#5.7.1)
  • 553 sorry, that domain isn’t in my list of allowed rcpthosts
  • 553 sorry, that domain isn’t in my list of allowed rcpthosts (#5.7.1)
  • 553 sorry, the recipient in not a valid user on this domain (#5.7.1)
  • 553 sorry, this recipient doesn’t exist.
  • 553 sorry, this recipient is not in my validrcptto list (#5.7.1)
  • 553 sorry, your envelope sender is in my badmailfrom list (#5.7.1)
  • 553 Your email address is denied.

Resolving a 553 email error bounceback

The 553 series of errors would typically be a hard bounce, and usually your message is rejected right away. For a better understanding of a soft or hard bounce is, and general email bounceback errors you can read why does email bounce, bounceback, or error?

In our example bounce-back error above the reason the message has failed is because of a misconfigured auto-reply that has failed to first authenticate with the mail server before attempting to relay a reply to a message.

Mine keep displaying this message:

“Warning: mail(): SMTP server response: 553 We do not relay non-local mail, sorry. in C:\xampp\htdocs\***************\*******\******.php on line 33”

I’m sorry to see that. Typically updating your SMTP settings in that PHP script will correct the error.

Message not sent. Server replied: Unknown response
533 sorry, your envelope recipient has been denied (#5.7.1)

That error indicates that the user is invalid. We would need more information to investigate the issue. We would need the exact error message you’re getting, the recipient name, and the account name (if you are an InMotion Hosting customer). If you wish to handle this issue privately please contact our live technical support team via a support ticket. If you’re not an InMotion customer then we recommend that you contact technical support team supporting the server hosting your email.

Great post, but I’m running into a 553 that I can’t seems to be outside of the norms:

Error occurs with both Outlook and OWA

Error only occurs with when sending to a specifi domain

Manual telnet returned the same error:

Requested #553 Requested action not taken: mailbox name not allowed ##

Any guidance would be appreciated!

I have seen this caused by a malformed email address being created by a mailing script. I recommend reviewing your mail logs for additional clues and also checking your server’s mail filter settings.

Thank you,

What does it mean when you receive an email stating “Undelivered Return to Sender All Messages from (then my IP address) will be permanently deferred Resending will not succeed” Does this mean the recipient has blocked me from receiving emails from me?

It means the server suspects your IP of spamming and they are deferring all the emails you send.

Thank you for contacting us. Since the error code specifically mentions SMTP authentication, and a 553 email error is normally related to SMTP authentication not being used. I recommend checking the outgoing mail settings (SMTP) with your mail server, to ensure they are correct. If you are hosted on our servers you can view your email settings in cPanel at any time.

Thank you,
John-Paul

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:

The error that the other server returned was:

What do I do, I am using gmail with chrome8 windows 7..

Basically, the server that received your email could not deliver it. You are not on the list to send emails to the address specified. There is little or no chance of resolving this issue without contacting the recipient and having them whitelist you.

It appears that you are using a mail relay. The error basically says that “relaying” is blocked, so that type of process is not allowed for emails. We host emails but we don’t provide support for email setup on an AS/400. You may want to find a more appropriate community or online forum for further assistance.

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