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] 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!
