Having some issues trying to get something working on postfix.
That is, I have a domain abc.com which is a destination domain on my postfix server 1.2.3.4, it hosts mailboxes for addresses in this domain locally by default - straight-forward.
However, I would like to be able to "relay" specific email addresses from within this same domain (say: userx@abc.com) to another postfix server [5.6.7.8]:2525 - yet still retaining the original ability of being able to deliver mail to all other addresses *@abc.com locally on my original postfix server 1.2.3.4.
Is anyone able to advise how I can go about doing this?
Thanks in advance!
Update 1:
...still have one issue.
So I have transport file:
userx@abc.com relay:[5.6.7.8]:2525
*@abc.com local
And main.cf:
relay_domains = abc.com
This config sends to the relay perfect as I want, but any other addresses (in the wildcard scope) do not get delivered as they try to go straight back out the default relay server (another server altogether), where-as instead I'd like them to hit /etc/aliases or a local mailbox.
