I'd guess the processing sequence is different.

I doubt it; the whole point of cuthrough is that you don't generate bounces. -- Cheers, Jeremy -- ## List details at https://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/

Re: [exim] data timeout on connection
Slowly mails from this afternoon roll in... Hope my excitement is not too early, but whenever I happen to learn what has been spooking there, I will let you know. Thank for your head ups. Still would like to know what the hummus server's log had to tell about the timeout.
