The comment at
<https://bugs.launchpad.net/mailman/+bug/1154004/comments/7> suggests a
way to use header_filter_rules to make sure the Sender: (if any) and
From: addresses match. Assuming your MTA is standards compliant and puts
the envelope sender in a Return-Path: header, you could use something
like that. It would have the advantage over Sender: in that Return-Path:
would always precede From: and you wouldn't have to worry about the
other order.

Still, a custom handler <http://wiki.list.org/x/l4A9> is probably more
robust.
