You're probably doing postmaster or header_sender callouts with a non-empty reverse-path, which is unfortunately Exim's default. Use the use_sender option on your callouts to make your mail server behave more sanely. Your description of John's behaviour is untrue. It's not that he rejects all mail with empty reverse-path. It's just that he doesn't accept mail with empty reverse-path if the recipient is an address which never sends mail in the first place and hence should never receive bounces. -- dwmw2 -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
