I think this line is where the problem is. Don't you ?
you know the problem with SMTP... because of spamming. It could be the cause...
in /var/log/mail.log I have, for example (the last try):
Jul 13 02:46:00 new-host-2 postfix/smtp: B50AE9E7822: to=<email@example.com>, relay=none, delay=16, delays=1.1/0.01/15/0, dsn=4.4.3, status=deferred (Host or domain name not found. Name service error for name=gmail.com type=MX: Host not found, try again)
Jul 13 02:46:43 new-host-2 postfix/master: master exit time has arrived
Hope you understand something!
Is it my port which isn't open ?
