[Mailman-Users] How to stop these Non-sense mails?

[Jonathan Dill]

Two things you can do with Mailman though, depending on your version of 
mailman:

1. if you don't need to allow non-members to post to the list, you can 
set the default action for non-member posts to "discard"

2. set up something like SpamAssassin, and then set up filters based on 
the SpamAssassin headers, for example "X-Spam-Flag: YES" is just discarded

I have #1 and #2 set up, so 99% of the time I just get an "autodiscard" 
notification, but I don't have to go into the admin interface and 
discard the posts there, so it saves a little time, plus these garbage 
posts aren't "piling up" waiting for me to moderate them.

Lastly--this is a web server thing and not a mailman thing--you may want 
to improve the security of your web server set up to prevent spammers 
from collecting the mailman admin addresses from the web interface, for 
example switch to SSL with at least a self-signed certificate, and 
restrict access to the web interface if possible.
