Sounds to me like you're doing anti-spam/anti-virus filtering after the 
mailing list.  Don't do that.

Do all your filtering on inbound, and then set up another instance of the 
MTA with all filtering turned off, and listening only to a certain 
designated private high-numbered port on the loopback/127.0.0.1 interface, 
and then set up Mailman to use this second instance of your MTA for sending 
all outbound mail.

I'm sure this is covered in the FAQ.
