I run a Sun Cobalt RAQ 550 with Mailman, and about 90 lists. I have a few users, on various lists who are subscribed to a given list, who can reply to an existing message, but who can't post an original message. they are then rejected as a non-member. Any ideas?

There must be some difference in headers or envelope sender between a reply and a new message in these cases.

Have the user(s) both send a new message to you rather than the list and reply to a list message but re-address the reply to you. Then look at headers in these messages. Look at From:, Return-Path: (which reflects the envelope sender), Reply-To: and Sender: which are the addresses used to determine list membership (assuming you haven't set SENDER_HEADERS in mm_cfg.py).
