Hi,
We have setup grommunio with the iso image. The wizzard generates many system-wide configuration files.
Primarily we need to modify postfix configuration to reflect some corner-cases in our setup (individual transport-maps, tls-policies, special bounce_messages, sender_restrictions, additional ports in master.cf for individual senders).
What is the recommended way to do so to not break any future updates?
with other words, what is the way grommunio way?
thank you.
