[Mailman-Users] Emails sent directly to "bounce" address

Is there any way to filter these emails sent to the bounce address so
that if they are spam they just get discarded.

Procmail, ClamAV, etc. You should be running such filters on all received mail. If you can't reconfigure the MTA to do this for some reason, the admin can usually run procmail through his/her .forward file.
