[Mailman-Users] Help?

[Judys Email Lists]

I am relatively new to mailman and am running about a dozen lists.  One 
of them seems to have been picked up by the spammers

prtspecials-owner at mail.trest.com
prtmembers-owner at mail.trest.com

Is there any segment in the software I can change that will bounce these 
messages and yet allow legitimate messages go through?

I am running Mailman on LINUX Fedora Core 11 using send mail and Mailman.

Thanks
