Hi, I have a postfix server that acts as a relay server for several domains and relays e-mail to several external e-mail servers based on the domain. This setup has been working for years with no problems. Now I have a need to install a local mailserver (dovecot?) server on this relay server and I'm trying to figure out the best way to accomplish that. So in the end, I want to maintain the relay ability for the several domains to outside e-mail servers but I also want to be able to deliver e-mail to local mailserver with ideally virtual users.
Is this possible and what would be the best way to accomplish this? Thanks a lot in advance.
