I'm migrating a previous server which I managed manually to a new one which I have installed ISPConfig upon. Previously I had several rules in the postfix virtual file which redirect some mail aliases to multiple mailboxes, in some cases to addresses on external servers (e.g. info@domain user1@externaldomain,user2@externaldomain). Is it possible to create this setup using ISPConfig3 or is it possible to set this up manually without causing problems?
Thanks. I guess the purist in me wanted to keep everything managed in the same place but I guess it doesn't matter as long as it works.
