How to configure connectors and edge transport server?

Question

Microsoft Exchange

Good afternoon. I have an Exchange 2010 mail server and it hosts several mail domains. At the moment there is one working relay on postfix and one non-working edge transport 2010 relay. Is it possible to configure the system so that, depending on the domain name, mail goes through a specific relay (each of which has its own external ip)? It is possible to put as many edges as needed. Thank you. I would be grateful for information or links (websites/books).

Answer 1

The task is not very clear, nothing prevents making a postfix - edge - exchange chain. It's
just that usually a subscription is created for the edges, which is in the dmz, adam is raised on it, this subscription creates two connectors, one for outgoing mail outside, the second connector for the extensions that are in your network.
Those. By default, all mail in ekschendzhi is routed to edges, which already route mail outside, but to a specific domain - you can route them as you like.
