Hi all. I need a little guidance on a problem I'm having with RT 3.8.2 using Postfix as the MTA.
The issue is that replies are not sent from RT when an external alias is used; these messages are identified as bounces because their 'Return-Path' header is empty. Replies are sent without incident when the actual address on the RT server is used. I do not have control over the remote server's configuration (running Microsoft Exchange). I do have control over my own Postfix server. The basic configuration is as follows: [email protected] -- RT's queue address (for the Support queue) [email protected] -- Remote alias used for convenience The [email protected] address points to [email protected] by way of a "Distribution List" which contains only one "Contact", the target address. I'm told this is how one creates an alias on Exchange without having to create a new mailbox. When Postfix receives mail by way of the alias the headers look something like this: >From MAILER-DAEMON Wed Feb 4 14:21:39 2009 Return-Path: <> X-Original-To: [email protected] [etc.] I do see the original destination address further down but that's expected since the message has to originate somewhere. When Postfix receives mail sent to the actual local address, the headers are more complete: >From [email protected] Thu Feb 5 09:36:41 2009 Return-Path: <[email protected]> X-Original-To: [email protected] I realize this may be a Postfix question but I'm just not sure where to start... My understanding is that the local delivery agent is responsible for setting the "Return-Path" and "From" headers but I assumed Postfix would do that if necessary. It is doing this for messages sent directly to addresses. The remote server is not setting these headers; I verified by sniffing the SMTP session. Any suggestions would be most appreciated.
