[Mailman-Users] Spoofed Addresses

[Tokio Kikuchi]

Hi,

I don't use bogofilter but use spamassassin to filter incoming messages.

With this aliases setting, the incoming messages will not pass through
procmail and bogofilter. You should either set up aliases to be handled
by procmail or activate filter option in postfix.
Web documents like
  http://www.advosys.ca/papers/postfix-filtering.html
and of course your friendly postfix manual may be helpful.

Or, you can add a SpamAssassin.py like handler in Mailman/Handlers.
(As SourceForge is currently down, so I can't give you the id but there
is a patch in the patch tracker.)

This, I believe is a bogofilter question. How do you set up the rules?

Address and _header_ validation as well as attachment filtering can be
handled by Mailman. You should browse through privacy/filter options.
