You will want to check your DNS and try to telnet to the server. If
your server is behind NAT or you run split-dns it would be advisable
to try it from another connection.
dig mx yourdomain.com
telnet smtp.yourdomain.com 25
Of course if your mx record points to something other than
smtp.yourdomain.com you will want to use that instead.
