Postfix: Lost connection while receiving initial greeting
First of all, thank you in advance for your help. I had a server running Ubuntu 10.10 with postfix as MTA and mails were being sent out. I just replaced the server wih a new one running Ubuntu 12.10 and suddenly no mails are sent out.
postqueue -p output yields:
(lost connection with mail.example.com[10.XXX.XXX.49] while receiving the initial server greeting)
However when I try telnet 10.XXX.XXX.49 25, I am connected to the mail server and I can send a mail using ehlo, mail from, rcpt to etc.
Any idea what may be wrong?
