Server rejecting mail

[pserafin]

All,


I have no idea why my mail server has started reacting the way that it has, but this is the situation. I am runnin a 3.6 Messaging server on Solaris 2.6. After a reboot recently, the server started rejecting outgoing emails that it claims to have bad return addresses. I am not sure what this error means and I cannot see a return address in the mail header. The error returned to the user is below:

This Message was undeliverable due to the following reason:

Your message was not delivered because the return address was refused.

The return address was '<xyz@sompelace.com>'

Please reply to Postmaster@mail.sompelace.com
if you feel this message to be in error.


If anyone has any input, advice, or suggestions, I would greatly appreciate your help.

Pete

You need to post the entire error message first.

I am having a similiar problem. My server will send mail out just fine, but for some odd reason, it is rejecting incoming mail. The notice is stating that &quot;550 5.7.1 Relaying not allowed&quot;. By any chance do you know how to turn it on?? Thanks in advance.

As for the &quot;return address was refused&quot; message, it could be that the destination e-mail server is rejecting the message. We've had that problem periodically with mails destined for AOL users. You send the message to your messaging server, and when it tries to send on to AOL, if the AOL server refuses it, you may get that message. You may have to check the SMTP logs to see where along the line this happened. It won't be obvious, other than you should see your server trying to deliver it to the other server. If the rejection message comes in after that point, you can probably bet on that being the cause.

As for the &quot;relaying not allowed&quot;, maybe your server lost track of its relaying configuration. What messaging server, and what version are you using? If the domain you're sending it to (such as somedomain.com, for a user somebody@somedomain.com) isn't considered local to your server, you'll likely get that message. Perhaps it lost its local domains? An MX record could be pointing to the messaging server, but if the server doesn't know it's supposed to accept mail for that domain, that's considered relaying. And if you don't pass the relaying tests, it'll be rejected.

Hope this helps!
