[Mailman-Users] Mailman and Postfix Best practices to avoid fake senders

[Dimitrios Karapiperis]

Hi all!

I am still investigating ways how to eliminate the danger on malicious 
postings on a moderated list (announce-only - newsletter) by
forged sender or From addresses.

Except from the moderation,
are there any ways on the MTA side (postfix) asssting on this situation?


thanks in advance
Dimitrios
