It basically acts as a front-end to your normal MTA. First of all, it provides a convenient way to add SMTP AUTH support to any MTA. But the main goal for this project is to implement an SMTP submission server with full support for the LEMONADE profile (https://tools.ietf.org/html/rfc4550). It acts as a proxy server, so it doesn't queue anything; once the client sees a success reply for the message submission, it is already accepted in the actual MTA queue.
I have one remark and one question:
Remark: Don't forget XCLIENT / XFORWARD support to help the "real" MTA understand who it's really talking to.
Question: Will the new SMTP submission code somehow solve the robustness issues with sieve doing SMTP submission? We talked about it last November. Subject was "[Dovecot] Sieve puts incoming message into inbox on any problem with submission_host".
