Iíve set up a mail server following ďThe Perfect Setup - Debian Etch (Debian 4.0)Ē how-to and all worked fine until today.
From this morning I can no longer send mails to other domains but I can send them locally and I still receive mails from everywhere.
In my /var/log/mail.log
, each time I try to send mails outside, I see messages like the following:
Jun 15 23:37:37 mail imapd: Connection, ip=[::ffff:127.0.0.1]
Jun 15 23:37:37 mail imapd: LOGIN, user=thavaht, ip=[::ffff:127.0.0.1], protocol=IMAP
Jun 15 23:37:37 mail imapd: LOGOUT, user=thavaht, ip=[::ffff:127.0.0.1], headers=1334, body=0, rcvd=311, sent=3424, time=0
Jun 15 23:37:59 mail postfix/smtp: 4EE961E1A8A: lost connection with gmail-smtp-in.l.google.com[18.104.22.168] while receiving the initial server greeting
Iíve walked around several Postfix articles and googled for this message all the day with no success. Need a help.
