There is a recent thread on this in the archives. See the entire thread
starting at
http://mail.python.org/pipermail/mailman-users/2005-June/045186.html

If (one of) the regexp(s) in header_filter_rules matches the subject of
the owner notification - "%(listname)s post from %(sender)s requires
approval" - the owner notification is held again, thus the loop.

If you have something like [spam] in your regexp(s), make sure the
brackets are escaped - \[spam\]

There may be a problem matching the X- headers as well. in 2.1.6,
header_filter_rules matches the sub-part headers too. It shouldn't
match an X- header that only existest in the content of a
message/rfc822 sub-part, but maybe there's a problem here.

Also, does the message to the -owner address go through Spam Assassin
again? If so, you may have to arrange for it not to.
