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.
