We are dealing with a similar situation now. Some member,
or non-member, is spoofing the From: address of members to
post to the lists. We have full emergency moderation
turned on so all messages are reviewed before posting.
And at the MTA we have instituted various other checks
that help prevent messages from getting to Mailman. There
is no (easy) technology now that can prevent this. If the
person is inclined to make trouble, they will. If not
through the lists, then by some other means.
Fundamentally, its not a technology problem.
