I'm using a EC2 windows 2003 instance. I managed to install pop3 and i can connect to it locally (using outlook express with the remote desktop) and the server address is the machine name. I also added MX record on the DNS (mail.mydomain.com) but still i can't connect to the pop3 server remotely using either mail.mydomain.com or even the server IP.


The first thing that comes to mind is your firewall, have you opened port 110 on your firewall?

  • yes, port 110 is opened on both server and EC2 security settings. – Que Jan 1 '10 at 19:39
