[Mailman-Developers] Making the anonymize option really anonymize

[Kristoffer Gleditsch]

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.
