I presume that I'm being a bit too literal in reading something, but here's my question anyway.
I am setting up an i-MSCP configured system for host client webspaces. We already have existing email infrastructure and will continue using it. As the master admin (root) I'd like to be able to get my own system messages (once forwarding is set via the aliases file) and my customers will want their websites to send email via our existing smarthost (which does virus checking, logging, etc).
What do I need to get i-MSCP to not remove / overwrite a plain "relayhost = smarthost....." line in the postfix main.cf file? This is the in-house server so there's no authentication going on.
