That's exactly what I want.
Forward those inbound messages for a single mailbox.
If I use the file pickup option, I can access all inbound messages. They are stored in a specified folder. I can see the message and it is logged on PMTA Console (Time it arrived, the mail from address)
But when I change all the config for relay-address, it stops to store messages in a folder, but it do not send to the mailbox specified, it is no longer logged on PMTA console and I don't receive any delivery error.
=/
This relay-address have any other directive, that work together?
