[Mailman-Users] Fake Email

[Geoff Shang]

Hi,

HOw would you propose such verification of the authenticity of a sender be 
performed in Mailman?

It's hard enough to do anyway, but as has been pointed out, it's probably 
more the function of the MTA than of Mailman.   The MTA can do things like 
insist on client-side certificates and other such measures which may or 
may not be helpful, and would have the advantage of screening out such 
Emails for everyone served by the mail server, not just the mailing lists.

Geoff.
