The sender reported in the post log messages above comes from either
the From: header or possibly the Sender: header (if
USE_ENVELOPE_SENDER is set true in mm_cfg.py) of the incoming message.

However, membership tests will test all of the From: header, the
envelope sender (unix From_ or Return-Path:), the Reply-To: header and
the Sender: header, and if any of these contains a member address, the
post is deemed to be from a member.

If the original Reply-To: is stripped by the list, it is lost, but the
other information is in the message in the
archives/private/LISTNAME.mbox/LISTNAME.mbox/ file.
