1) Got a spam apparently from [EMAIL PROTECTED]
2) TMDA sent a challenge to that address
3) The mail daemon replied to the "Reply-to" and not the envelope
This hasn't happened to me before. Is there a good way to avoid this happening again? In other words "how can I detect forged email addresses and not send challenges to them?" or "How can I detect a bounce sent to the reply-to instead of the envelope and have TMDA not even consider those for releasing a message?"
Here are some relevant headers from the bounce itself:
Return-path: <[EMAIL PROTECTED]> From: [EMAIL PROTECTED] Subject: Undeliverable: Returned mail: see transcript for details Message-id: <[EMAIL PROTECTED]> X-Loop: [EMAIL PROTECTED]
Do you think I can reliably filter on any of that stuff to detect "bad" bounces?
Furthermore, is there an RFC I can quote to the site admin for that bad daemon telling him/her to reconfigure to reply to the envelope instead of reply-to?
