message refused by my exchange 2003 server
Posted on 2004-10-04
I am running a single Exchange 2003 Server. I have one domain. I occasionally have customers mailing me get the following message:
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:
SMTP error from remote mailer after end of data:
host mail.mycompany.com [X.X.X.X]: 550 5.7.1 Requested action not taken: message refused
The message reached the recipient’s e-mail system but delivery was refused. Attempt to resend the message. If this still fails contact your system administrator. The MTS-ID of the original message is XXXXXXXX@notmycompany.com
mail.notmycompany.com #5.2.0 SMTP; 550 5.7.1 Requested action not taken: message refuse
So I logged on to an external account (Earthlink in this case) and tried mailing my company. Most e-mails go through the ones that don’t were messages that I tried forwarding with graphics (not obscene).
Everything I read tells me to check my recipient filtering. I also checked Symantec’s content filter policy. Does anyone have any ideas?
