I've received a strange request from management and I'm determined to make it work....I'm obviously running Postfix (along with ISPConfig to help manage it with virtual domains on Ubuntu Linux), here's what they'd like to do.
1.) Keep existing virtual domains the same (allow sending and receiving to the outside world as normal) 2.) Create a new virtual domain (xyz.com), but allow only certain domains to email virtual users in this domain (so traffic from test.com -> [email protected] might be allowed, but traffic back to test.com from [email protected] might be disallowed). Essentially, we'd like to control what comes in and out of our domain (yes I understand this can be spoofed) and any mail inside this new virtual domain should be attempted to be delivered to a local virtual user in this domain otherwise if it's allowed to be delivered outside, then do it. Does all this make theoretical sense? Is it possible?
