Subject: Port 587 submit setup
A friend is trying to set up a Postfix submit server on port 587, so
it requires SMTP AUTH but doesn't use the DNSBLs that his regular port
25 server uses.
This is surely a FAQ, but we must both be very nearsighted because we
can't find it. Can someone remind us where it explains how to set up
a SUBMIT server with a different config from one's regular server?
Tnx,
John
