The list-owner of one of my lists is getting spammed. Is there an easy way to block that? TIA.

Privacy options... --> Spam filters --> header_filter_rules apply to mail to list-owner as well as to list, so the owner may be able to use those to discard the spam.
Otherwise, you need more effective spam filtering in the MTA ahead of Mailman.
Hi,
I was having this happen, but in my case there was a very easy way to get rid of it. Whoever set up that spam mailing list made a very big mistake. They chose to send their spam to the owner address *and* the address for posting to the list! Normally there is absolutely no valid reason for sending the same message to those two particular recipients, so I installed Milter-Greylist and set it up to block those messages at the SMTP level. Hasn't stopped the spammers, but at least my system doesn't have to process the spam.
If something like this is going on in your case, that might be an option. If not, and if the spam has nothing in common, as far as I know there's nothing Mailman can do in this situation, you'll need to employ spam filtering before Mailman sees the mail.

Hi Jason,
Thanks for the reply. I am using fetchmail to retrieve each mailbox. I am familiar with spamassassin but I don't think I can integrate that with fetchmail. I'm not sure what I could use.

Hi, Dennis -- I use fetchmail (for personal mail), but fetchmail normally delivers to a local MDA/LDA/MTA. Specifically, it can deliver using an SMTP protocol, or it can deliver over a pipe using the --mda option. So I invoke "fetchmail --mda maildrop" (maildrop is an MDA developed by the Courier MTA/IMAP project, I think). I don't currently use maildrop's filtering capabilities, but I would suppose that to access Spamassassin I would use the "xfilter" capability of Maildrop. I've also used procmail, but the fetchmail docs recommend maildrop, so you might want to use that program.
You might also find that maildrop's built-in filtering is sufficient to your purposes. The advantage of SpamAssassin is that "crowd-sources" information about past spam -- if you were lucky, you update the SA rule set and automatically get protection from the most recent spam.
