Enable surbl in spamassassin.
My (Vserver) external mail server does this, and it will grab a lot of
spam seen on this list.
Most of the spam seen on the list I am automatically moving to my spam
folder based on surbl.
I won't touch SpamCop (and surbl uses SpamCop). They list too many 
sites, that
aren't spam. Even my server was listed there for about 2 days, because 
somebody
has reported a spam mail that went over the vserver mailinglist. 
Instead of
listing the originating mailserver for the spam, they listet the 
mailinglist
server.
then just do greylisting

These mails generate more off topic traffic than the spam itself.
A solution is being worked on, as i have said earlier, that should take the
very last pieces of spam on the lists, but Rome wasn't build in one day
and you just don't simply implement things without testing on a production system.

End of discussion.

 The funny part about this, IMHO, is that my spam filter catches all the
 spam to this list. So if it wasn't for people crying about it, I
 wouldn't even notice. And surely I can't be the only one in that boat.
 
 I guess I could email Marc and talk to him about spam filters.

Sure.

The difference is, that you for yourself can filter spam quite aggressively.
On the server that hosts quite a lot domains mail and lists i can not do this.

Currently 95% of the spam send to this list is catched by the filters and i'm working
on the improved whitelist feature, that should take the last 5%.

But until then people will have to live with the occassional spam post.

Kind regards,
Martin List-Petersen

have you considered using greylisting?
It works by temporarely rejecting messages (the first time) and 
allowing the 2. time.
usualy spammers dont resend.
Greylisting should save bandwidth as well.

And that was not a one time scenario. As I said: I have more users to take care
of than just myself and i can not risk to filter valid mails away.
