Hi,

We have a setup where we need the anonymizing feature "Hide the sender of a message ..." to actually anonymize the messages going through the list. Both in the archive and in the mails it sent out, it left headers that (normally) make it pretty easy to track the sender. This patch against Mailman/Handlers/Cleanse.py from version 2.0.11 should remove most of those. It strips the recieved-headers, generates a new Message-ID and sets the envelope-from address to the list admin.

Regards,

Kristoffer.
