Issues with using MajorDomo with ProcMail/SpamAssassin

[popasmuerf]

I have a sendmail box(Debian Linux) that is functioning as a listserv using MajorDomo. I noticed that some of the lists on the box where recieving spam to I decided to clone the box (this on VMWare), install ProcMail/SpamAssassin and do some tests for mail filtering. The forwarding and filtering of mail works just fine for "real" accounts on the machine but fails for sending mail to the address on all the lists on the test box.

I have reasearched this for about a week and I can say that I am fairly stumped. I suspect it has something to do with procmail but I am not sure what. Would any of you guys have any ideas or sugestions ?

Thanks in advance!!!
