Hi, I have setup a mailman server using postfix works fine using relayhost
However I want to split traffic such that our internal email addresses go to office365 while the rest go to another postfix server for delivery out into the internet. My problem is when I enable the transport functionality instead of the email to a list going to mailman ie the list it gets re-directed to the other postfix server, which sends it back and we get a mail loop. Obviously, I am missing some config but I have no idea what. regards Steven
