The address in the post log entry ([EMAIL PROTECTED] in this case) is
not necessarily the address which was validated for the list. There
are various possibilities, but for example, the address in the post
log entry could be the From: header address while the address that was
accepted as a member could be the envelope sender (or unixfrom)
address.

You may be able to get the incoming envelope sender from your MTA logs.

Also, if the list password has been compromised, the post could have
contained an Approved: header/line.

Both the original envelope sender and any Approved: header/line are
gone from the post as received from the list making it difficult to
diagnose this.

Still, looking at the post as received from the list might reveal a
Sender: or Resent-From: or other header that might have a member's
address.
