unfortunately that is not currently a feature, are you trying to relay messages out of Postal or do you have an SMTP receiving service you'd like Postal to pass messages it receives to.

This functionality would be very useful and secure.
To the smtp relay, it allows some protection against spoofing.
It also allows application and database servers to send mail from an internal relay to an external one, applying access rules by IP/credentials, allowing certain sending addresses, mapping to end points (http or smtp) for each destination/sending address.
In my case the mailtrap service requests authentication.
