Postfix is recognizing that the origin of the mail was an attempt to act as if the mail came from the user it was intended for.

Can we have it? :-P I know of tools to analyze the current postfix queues (qshape and pfqueue), but I haven't used any tools yet to gather historical stats. 2) You say: "One of the major reasons that messages are deferred is that your server is going to place mail to “unknown recipients” into the deferred queue if they do not have a legitimate user to go to." Maybe I'm wrong, but if there isn't a legitimate user to deliver the mail to, wouldn't postfix bounce the mail instead of putting it into the deferred queue? I think the deferred queue is only for mail which has permanent problems (eg because of greylisting), while a permanent problem causes a bounce. Regards, Stijn Hi,
