Postfix deferred the message, because it accepted it in the first place. Then Postfix - trying to deliver the message - passed it on to LOCAL_MDA[aaa.bbb.ccc.ddd], which rejected it. Therefore Postfix deferred the message, because LOCAL_MDA[aaa.bbb.ccc.ddd] responded with a 4xx error code. So postfix will keep the message in queue and retry to deliver it. For IP addresses not in $mynetworks, Postfix should outright reject the message without trying to deliver it. -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub."
