Forwarding ... is GROSSLY insecure and causes far more problems than it solves. Just grabbing the traffic from the original INBOX with IMAP or POP3 is a much more secure solution.

Forwarding has worked just fine for 30 or so years, if not longer. The "problem" only happens if you insist on attaching SPF to it. If a car manufacturer had been making perfectly usable vehicles with perfectly functional windshield wipers for decades, and you discovered that the windshield wipers tend to malfunction when you attach other devices to the windshield, is that the fault of the windshield wipers, or the other devices? > Since every email client out there can check multiple mailboxes, if > you want to properly take advantage of SPF as a recipient, don't do > email forwarding ;) No, what you meant was: If you want to properly take advantage of SPF as a recipient, ensure that no users at other sites set a forward to your mail system if their sysadmin has set an SPF record that will cause problems. Which is, in general, obviously not achievable. _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
