I've added a domain name which has email addresses that are only in the virtual map. There are no real mailboxes over on Dovecot (via transport) for this one. Attempts to send mail to postmas...@newdomain.example.com gets "Relay access denied", so it clearly doesn't recognize the domain (I didn't put it anywhere, so how could it ... depending on the virtual map for that would not get the right error message for bad LHS in that domain). So my question is, which map does it go in if all it is used for is addresses in the virtual map (being forwarded to real mailboxes in another domain).
I'm doing this on a 2nd test server, for now.
