My 2 cents.
This thread smacks of trying to adapt Mailman to be an anonymising
remailer and I am not sure that is a suitable objective.
Brad is right in saying that suppressing all information alluding to
the originator of a posting requires gutting the message of a fair
number of headers of value in dealing with mail problems. Not just
From: and Received: but Message-id: and others have to go.
As regards spammers acquiring email addresses to target, list archives
are probably a bigger target. A while back (MM 2.1.3) I took a punt at
some fairly aggressive measures to limit harvesting of email addresses
from Mailman list archives. The patch works but I have no idea if any
people found it of interest. See:
