thank you. That was exactly the clues I needed. the problem seemed to be related to a friend of mine running mailman list on virtual machine here. We were having all sorts of problems with SPF message rejection and when we tried: SENDER_HEADERS = ('sender') the problems went away (why? I have no idea). so, I copied and got bit. It's probably additionally some interaction between postfix and mailman in terms of what gets sent in the SMTP transaction but what the heck, it's working now and I can live with it. thanks again for the help. ---eric ------------------------------------------------------ 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
