Well, what does `Operation timed out` tell you? Contact your network administrator, this is a network issue. Probably port 25 blocked.

Re: Email getting deferred

If your mail servers are behind firewall than thay will not solve your hostname with public IP and you will get timeout error...

To get rid of this you should have a local bind running on your server .
