Are you sure that: - your mail server gateway name resolves into your mail server gateway IP and - your mail server gateway IP reverse resolves to your mail server gateway name Both should be resolve properly. The check should be done outside of your own subnet, from an Internet Cafe (use Windows nslookup command, same syntax as nslookup on Unix) from home if you use a different ISP than for the machine that makes problem... You mention that you recently changed your IP, how recent is that recently? The old IP/name could be cached at FreeBSD. Bests, Olivier
