Postfix and SMTP
I'm trying to find out if it's possible to force Postfix to send mail out past itself when the destination domain is the same as the mydestination option in the main.cf file. Basically, I have this test mail server that we're trying out. It's also running as an outgoing mail server for some scripts to send reports out to a lot of people, so I can't really relay the mail through a different server, as it's an awful lot of messages to relay. So, I was hoping that for testing purposes (as it's not our primary server yet) I could find a way to set in such a way that I could send messages to our domain name from this test server and have them arrive to our current mail server.
In thinking about it, I thought that removing the domain from the 'mydestination' option in the main.cf file might do it, as then it wouldn't think it was the final destination for all mail at our domain. But, before I made that change, I wanted to check to see if anyone knew of an option that would force all mail to go out to the internet, no matter the destination domain.
TIA for any advice.
