Well, being tired of spam sent to the list, I've set up a filter before I
send them to my procmail folder
Why not just INCLUDERC your junk mail filter before the recipe that
checks for list mail? That seems much simpler than a dedicated
listkeeping filter for the procmail list.
Many of my spam tests would not work well for mailing lists. (I
dislike Bcc's; stuff sent to usenet addresses not in reply format,
etc, etc.) I have recently split my suspicious/spam tests into
three groups.
First is duplicate checking, which includes finding invalid
message IDs, and some fun metrics with my hashd program. Not
super effective on normal mail, killer on moderator alias mail.
My empty message-ID test killed that recent spam.
(Next I handle all my forwarding and scripts, including the
moderated group stuff.)
Then I have "pre-list" filtering, copy included below.
(Then my lists get sorted to their proper places.)
Finally my rest of it filtering, largely unchanged from the copy
from <URL:http://www.netusa.net/~eli/filtering.html>, save that
some of the stuff got moved into pre-list.

prove to you my mail is not spam, if mail to you bounces it will not be resent.
