I was wondering if it's possible to notify users who have had messages distributed in the same way that if a user gets rejected they get a notification.
There doesn't appear to be any way to turn the feature on.
I have a scenario where I need to blacklist emails from one email to one of our local emails. Is blocking this specific scenario possible in postfix?
For example, emails from [email protected] to [email protected] should be black listed, but not other emails coming from [email protected].
