[Mailman-Users] Preventing spam to list owners

[Gary Spivey]

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 at 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 at my

.domain.com>, size=2069, class=-60, nrcpts=1,
msgid=<mailman.23.1190569172.40

86.mailman at 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.
