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
