There's no signs of an error message resulting from Exchange actually talking to a MX server for freebsd.org, just a queue timeout on your side.  I'd guess that your Exchange server is broken somehow, perhaps from your ISP blocking port 25, but there isn't enough useful information for that to even be more than a guess.

If you know sendmail, for testing purpose set that up and have Exchange relay external email via your copy of sendmail.  At least that would provide some sort of useful logging or a DSN...
