Ok, so I've followed your tutorial thoroughly and had success. Now if I wanted to catch all mails going to domainA, and send them to smtp.domainA.com, what scenerio would i have to use? Would it be a transport: domainA.com --> smtp:mail.domainA.tld?
Also, If I wanted to catch emails going to domainB, for specific users, and send them to domainA, would I have to use the forwardings example below?
. You have .tld in your examples, do I have to create the destination as user@domainA.tld
? I'm a bit confuse as to why .com is not used.
