Messaging Gateway

Hello, I've just setup two 8340 Brightmail gateways, software version is 8.0.3-11 Today some users are receiving these messages: --- Da: Mail Delivery System [mailto:Mailer-Daemon@itsaspam01.diasorin-eur.it] Inviato: martedì 26 gennaio 2010 15.41 A: <username> Oggetto: Delayed Mail (still being retried) #################################################################### # THIS IS A WARNING ONLY. YOU DO NOT NEED TO RESEND YOUR MESSAGE. # #################################################################### Your message could not be delivered for 0 days, 4 hours, 0 minutes. It will be retried until it is 5 days, 0 hours, 0 minutes old. For further assistance, please send mail to <postmaster> If you do so, please include this problem report. You can delete your own text from the attached returned message. <<username>@diasorin.it>: 450 4.4.1 [internal] Connection Timed Out --- Attached I found a clearly spam message in which the sender's address was the same as the recipient's (a user in my organization). When this delay message is sent back to the sender, it instead arrives to the user. So what I'm asking is: is it possible to disable such notification but only for e-mail messages considered as spam or suspected spam ? Thank you ! Regards, Diego

Hi Diego,

You can block messages coming to your organization from senders (spammers) outside your organization pretending to be from your domain.  Here is a KB article that provides some suggestions:
