I got a bounce myself. But this time it wasn't from us, it was from the
perpetrator host. Sigh. Fortunately, it had enough information for me
to identify and remove the subscriber.
Look at your headers from list mail. You should see something like
Return-Path: <slackbuilds-users-bounces at slackbuilds.org>
That's what Postfix adds; that is the envelope sender.
Our rogue subscriber had some sort of braindead filtering script which
ignored the envelope sender, and reconstructed a NEW envelope based on
the headers. That's why the messages were being reposted and bounced;
this script sent them.
Again, the subscriber is removed, so the problem is resolved until
someone else does something equally silly.
