Perl.org is looking for outside assistance to help remove spam from perl.org and/or cpan.org email. (i.e. we are interested in outsourcing our spam filtering.)
Today, our filtering consists of SpamAssassin, qpsmtpd, blacklists (like IVM), and a ton of custom rules. But still spam gets through. The perl.org mailing lists even have human moderation as a last line of defense.
We try hard, but there's no way we can filter as well as a company that is 100% focused on it. If you represent one of those companies and think you might be interested in donating spam filtering services to us, we'd love to hear from you. Please email webmaster at perl.org. We'll sing your praises, add your logo to our list of sponsors, and more!
