Im trying to send emails from firstname.lastname@example.org from the MIAB server, to another email server with the @example.com domain. The MIAB server is setup with multiple domains (@example.com, @test.com). When I add the @example.com it doesn’t allow me to send any mail to the other email server (non MIAB @example.com server).
What Im looking for is a way to have all mail trying to be send to @example.com to automatically be sent to the other email server, it should never try to delivery internally. Does anyone know where this would be set at?
