Is there a way in postfix or otherwise that I can send a full envelope per domain?
I need to filter on destination domains and I can't do this properly when there is only one outgoing envelope. I need to selectively delete some of the recipient domains while allowing others.
I hope this makes sense. I have tried searching, but I'm not really sure what terms to use to find what I'm after.
I believe sendmail has some sort of functionality like this.
