On the python.org mail system, we do not accept e-mail from sites that don't have proper working reverse DNS set up for their IP address. However, we do not refuse connections from networks that are known to be within dynamic IP address space from major providers -- some of our own key people (like Barry) use dynamic IP address space, and we wouldn't want to reject their connections or connections from anyone else doing the same. So long as those addresses have proper reverse DNS set up for them, and they're not on one of the very conservative RBLs that we use, then they should be fine. IMO, this is a reasonable balance to strike. Most everything else we do is done within SpamBayes, which is a Bayesian anti-spam classification system written in Python, and maintained by various well-known people in the Python community (see <http://sourceforge.net/projects/spambayes> and <http://mail.python.org/mailman/listinfo/spambayes>). In this respect, we eat our own dog food, and run the same anti-spam processing system on our own machines as we provide for the benefit of the larger anti-spam community. -- Brad Knowles <[EMAIL PROTECTED]>, Consultant & Author LinkedIn Profile: <http://tinyurl.com/y8kpxu> Slides from Invited Talks: <http://tinyurl.com/tj6q4> ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org Security Policy: http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq01.027.htp
