The GNU Mailman mailing list software is a big offender in that area. The option to fix this is to set "respond_to_post_requests" to "No" on the main options page. Otherwise it is a serious backscatter source. I think the default may be Yes. respond_to_post_requests=No As a backscatter source I would have no qualms about listing them in a DNSBL. Reporting offenders as spam sources seems like the only recourse. > Any tips for filtering these out? I specifically filter those out from my incoming mail.

Unless you are the moderator you can't approve the posting. And if you are the moderator then you will get a moderator mail message concerning it and can react to it. It doesn't help you. There isn't any action you can take for it. So you might as well smtp-reject or procmail-discard those. > but I get a phenomenal number of such messages where it's obviously > a spammer who has sent a msg to the list and joe-jobbed me.
