Hi guys. I'm inheriting a job that has an email server hosting several domains, and I'm wanting to move them behind our firewall and route mail from the main mail server to an offsite postfix server that will in turn send them out to wherever they need to go, kind of like my own homemade smarthost. Because of security we need to keep it all in house, so a paid smarthost isn't an option. This postfix server will only take mail from the server and send it out, and return bounce/errors to the main host. It won't accept any incoming mail.I'm a postfix user and try to image your plan.

If this is what you said, then the "OFFSITE POSTFIX SERVER" is a relay only mail server. The "several domains" are the destinations.
