I have the same issue.  I get over 400-500 junk messages/day.  Wont this
create additional mail traffic since probably most of the mail are from
spammers without a real return path?   

1 - How can I  " | /dev/null"  mail from non members silently?

2- Alternatively, thinking of an announcement list how can I " | /dev/null"
mail from ALL BUT owners and editors (including members)?
