This sounds like the back-scatter issue ( http://www.spamresource.com/2007/02/backscatter-what-is-it-how-do-i-stop-it.html ) we recently experienced on our regular mail system.

Spammers spoofing a good email address from our institution to fire off a volley and the NDR's getting routed back to the us. Thousands were coming in every day.

We deployed a BATV solution at the edge of the enterprise  http://mipassoc.org/batv/

Could something like this be used in a majordomo arena?

Subject: Majordomo and spammers

I have recently moved my site to a new server using Q Mail, and reinstalled Majordomo.  I am having two problems.

 

1.  I am getting hit with a great amount of spam addressed to majordomo, which is generating replies to non-existent addresses, which in turn bounce back to me.  The replies are the standard reply from majordomo when it does not understand a message.

     Is there any way of stopping these replies from Majordomo or of changing the majordomo's address from majordomo @ domain . com?

 

2.  All of these spam messages to majordomo are generating zero content messages in the digest folder, which in turn, adds blank messages to the digest.  How can this be fixed?
