Hi all, I'm running a personal Postfix mail server together with Courier for a virtual domain setup.
By now I have a domains table with a single transport field which is used by transport_maps directive in order to know if incoming emails must be delivered locally or need to be sent to the next hop. The thing is I would like to be able to receive email for domain example.com, as i've been doing so far, but I also would like to be able to relay the outgoing emails for example.com to another domain like smtp-relay.gmail.com. So, after reading the transport [1] documentation I'm a bit confused. As I understand I would need to create a new field in the domains table called relay_transport and edit the $transport_maps MySQL query. If I understand it correctly, $transport_maps query's result should be the same as now but for those domains using an external relay the result should be something like virtual:smtp-relay.gmail.com, is it right? Also, I just wanted to ask: 1. Is there any misunderstanding in the previous logic? 2. Is $transport_maps MySQL query used in other postfix workflow that I may missed? I do not want to make changes before understanding their impact. 3. If I would have to add a user and a password for authenticating to the relay, which settings should I take into account?
