Does Amavis actually connect to 127.0.0.1 when injecting mail back to Postfix? If yes, then maybe you don't have 127.0.0.1 in $mynetworks It can also be that Amavis doesn't connect to 127.0.0.1, but to some other IP on your server - then you need to put that IP in $mynetworks too, or reconfigure Amavis so that it connects to 127.0.0.1 If it works with "permit", it should also work with "permit_mynetworks", provided that the value of $mynetworks includes the actual IP Amavis is connecting to. -- 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."
