I have a few requirements which seem to be opposed to each other, as what I'm currently doing is causing a mail loop and bounce. Here's what I'm trying to accomplish: 1) This server is a standalone server sending outgoing mail, it is not receiving anything other than locally posted messages 2) Messages need to come from "mydomain.com" (myorigin = $mydomain) 3) Messages sent to local 'root' account must be forwarded to a different account @mydomain.com 4) Delivery to all but a few domains is not allowed, and must be discarded
For #2 I'm using the already mentioned myorigin = $mydomain. This works as expected, but $mydomain is not listed in mydestination, so for #3 I am using the method mentioned here: http://www.postfix.org/STANDARD_CONFIGURATION_README.html#some_local (virtual_alias_maps) to deliver the root mail locally, and allowing the rest to go off to our main mail server. For #4, I am using transport_maps (which was suggested in this thread http://archives.neohapsis.com/archives/postfix/2008-07/0875.html), and my transport file contains the following: mydomain.com smtp *.mydomain.com smtp * discard The problem I am seeing is that when I send a message to root using the local command "mail root", the domain gets added (as expected), then the virtual alias changes the to address to r...@localhost.mydomain.com, but then it is bounced because of looping. I've reached the edge of my current postfix knowledge, and would appreciate any input or suggestions.
