Block Outgoing Emails to all domains except one or several

eforulus

Hi tell me please, how i can block outgoing emails all domain except one or several, and can i different rule for different mail domains. As far as I understand i can this deal through global filter but i but I didn’t quite understand how I should register it, because all attempts completely broke sending mail. Or this need making through configure postfix?

Hello eforulus, would you be willing to share how you ended up configuring this in the UI? I’m having the same problem and I want to follow the advice of codec but I’m not sure how to do it. I would like to put in Transport Maps the following line, as advised by this blog post:

myspecialdomain.com:

But it won’t allow me to leave the second part blank. How did you do it?

Only configure a transport to the one domain you need and no transport to “*” within the Transport Maps.
So postfix has no valid transport to all the other domains, only the one needed.
This is within the “Configuration” on the “Routing” Tab.
