    One of my servers has stopped delivering bounced email to accountname@hostname.mydomain.com. I didn't change anything. The error message is:

    ---------
    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:

    accountname@hostname.mydomain.com
    SMTP error from remote mail server after RCPT TO:<accountname@hostname.mydomain.com>:
    host hostname.mydomain.com [216.38.xx.xxx]: 550 Unrouteable address

    ------

    Version is WHM 11.38.1 (build 13). I am on the release channel and automatic updating is allowed. My other server is on the same version of Cpanel and it still returns bounced sent by the server sendmail to accountname@hostname.myotherdomain.com

    I need the bounced emails to come to the accountname@hostname.mydomain.com because when a script on the server sends email to a bad address I need to delete that bad address from my list.

    Hello :)

    What email address are you using to send out emails to the "username@hostname" email address on your server? Does the sender's email address actually exist?

    Thank you.

    Let me try to explain better.

    A script on the server will send out an email to one of my registered users using sendmail. If the user's email address has become invalid since he registered the email used to bounce back to me via accountname@hostname.mydomain.com (example if the account name was blue and the host name was red.mydomain.com it would be sent to blue@red.mydomain.com). This has always worked for several years until it stopped a couple of weeks ago and now shows accountname@hostname.mydomain.com as unrouteable.

    I need the bounced email so I can delete the users whose email have become invalid.

    Thank you for your help.

    There may be some sender verification settings in the "Exim Configuration Manager" that are different between the two servers. Could you open a support ticket so we can take a closer look at the actual email addresses used and attempt to reproduce the behavior? You can open a support ticket via:

    Submit A Ticket

    Post the ticket number here and we can update this thread with the outcome.

    Thank you.

    To update, it looks like this was the result of an entry for the hostname in the following file:

    Code:
    /etc/userdomains
    The entry was removed from "/var/cpanel/users/system" and the /etc/userdomains file was updated via:

    Code:
    /scripts/updateuserdomains
    The intended email delivery address was then able to function as expected.

    Thank you.

    I am having this same issue. Not sure what entry I should remove from "/var/cpanel/users/system"

    I see an entry for user@host.hostname.com system in the /etc/userdomains file but not in /var/cpanel/users/system file?

    Any help would be great....

    Ok I did find a DNS1 entry for the hostname in the /var/cpanel/users/system and removed that and ran the /scripts/updateuserdomains

    Still getting the LOG: MAIN
    ** user@host.hostname.com: Unrouteable address issue...

    This all took place when I went to version 11.40. I have another server on 11.36 still works fine...


    Guess I should have not updated....

    I removed everything in /var/cpanel/users/system and ran update script and now it seems to be working as before.

    Thanks...

    I also have this issue. Never knew emails were not being bounced back until I looked at logs.

    What is the solution please? Can you just post here instead of raising tickets, would save a lot of trouble.

    Thanks
