It doesn't surprise me that the IP made spam DNSBLs because a fair amount of spam does get through to the list. It's not obvious that messages come from the list (one of advantages of subject tagging with list prefixes) so it's easy for people to report that spam to places like spamcop without realizing that it's list traffic. I think the list manager for this list is Mailman. It's easy to implement spamassassin checking in Mailman which would probably catch a large percentage of the spam that now gets through to the list. We run lists here with postfix and amavisd-new which traps worms that attack the Microsoft virus, Windows, and flags messages that spamassassin identifies as spam with headers that are easy to pick up with Mailman to forward to the list owner for approval.
