Hi! Recently i ugraded one more Debian server from Debian 5 to 6 and i upgraded ISPConfig too. Now i'm issuing problem with postfix i can receive mails but i can't send them. In logs i see this error message: server postfix/smtp: C16083940ED: to=<[email protected]>, relay=none, delay=481, delays=376/0.12/105/0, dsn=4.4.1, status=deferred (connect to alt4.gmail-smtp-in.l.google.com[184.108.40.206]:25: Connection timed out) It always show connection timed out, to every server (yahoo, live)etc... I don't have firewall, my ISP doesn't block any ports too... Regards!
