No hand-off from postscreen(8), this smtpd(8) is a direct "inet" listener.

This is the submission service on port 587. Not the inbound SMTP
service on port 25. No idea why google is connecting to port 587
on your machine, perhaps you have some sort of private arrangement
with Gmail to route mail for some domains via your own SMTP server.
On port 587, they probably want a trusted certificate.
