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: to="|/usr/lib/mailman/mail
/mailman owner mailman", ctladdr=<mailman-owner@my.domain.com> (8/0), delay
=00:00:00, xdelay=00:00:00, mailer=prog, pri=140071, dsn=2.0.0, stat=Sent
Sep 23 10:39:35 hostname sendmail[17247]: l8NHdZV9017247: from=<mailman-bounces@my
.domain.com>, size=2069, class=-60, nrcpts=1, msgid=<mailman.23.1190569172.40
86.mailman@my.domain.com>, proto=ESMTP, daemon=Daemon0, relay=localhost.loc
aldomain [127.0.0.1]
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.
