The first thing I would do is telnet *from* your mailserver to the FreeBSD mailserver and try a manual SMTP session and see what happens. If you get rejected then, you *know* it's a problem with the FreeBSD server. You probably know this already, but just in case: % telnet server.freebsd.org 25 HELO meltechsystems.net MAIL FROM: you@yourdomain RCPT TO: list@freebsd.org If all this works, then something else is causing the problem.
