[Mailman-Users] Preventing spam to list owners

My lists are locked down to only allow posts from members, so my members
are not getting any SPAM. However, as list owner, every one of my lists
is getting a large amount of SPAM - generally sent to the listname-owner
or to mailman-owner. My maillog entry looks like this:


Sep 23 10:39:34 hostname sendmail[17245]: l8NHdYwF017244:

/mailman owner mailman", ctladdr=<mailman-owner at my.domain.com> (8/0),

=00:00:00, xdelay=00:00:00, mailer=prog, pri=140071, dsn=2.0.0,

Sep 23 10:39:35 hostname sendmail[17247]: l8NHdZV9017247:
from=<mailman-bounces at my

.domain.com>, size=2069, class=-60, nrcpts=1,

86.mailman at my.domain.com>, proto=ESMTP, daemon=Daemon0,

Does anyone know how to best stop these? Are these SPAM's coming from
the outside direct to the e-mail address, or are they somehow going
through mailman? If the latter, can I stop it in mailman somehow? If the
former, does somebody have a recommended way to stop them? I have a SPAM
filter running on my end system, but I am just tired of the constant
flow of SPAM. 


Thanks for any help.
