Or, in other words, it just uses the original Envelope-From on the message, and forwards to its final destination(s) without mangling it in any way. To use the word 'forge', or 'forgery', for such a long-established behaviour is a new trend which has never really had any basis in common sense. I have plenty of "mailing lists" which are just aliases that expand to more than one recipient, and operate in exactly this fashion. Any user on my system can set things up that way, in fact, so that their mail goes to their local mailbox on one of my machines *and* some mailbox of theirs elsewhere for backup purposes. Perhaps they might forward it to their company email address, for easy access from within their corporate firewall. > > The company mail server is broken.

Not enough information. We do know that it is broken because he told us so explicitly when he said "my companies[sic] mailserver rejects messages coming from outside with a sender address from inside". That configuration is, quite simply, broken. -- dwmw2 -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
