Another measure would be to authenticate e-mail sent to the lists more
strongly, with signing it with PGP or S/MIME (digital certs). Signed
emails would be tagged as completely trusted, while others would go to a
moderation list, or just tagged as untrusted.
This requires additional discipline from us the senders of email of
course and this is a major drawback of this approach. But it seems we
will soon be forced to do that otherwise not too hard additional setup
of our mail clients to support PGP or S/MIME mail signing.
On the server side there is a project underway to upgrade Mailman list
server (which we are using) to support such authentication:
Secure List Server: Mailman, PGP and S/MIME
The Secure List Server: an OpenPGP and S/MIME aware Mailman
