I'm using Mozilla Thunderbird as a mail client, to read mail off my server. So anyway, I'm using Exim with cPanel 10, latest version, stable. I'm using CentOS 4.5, and Exim for mail, obviously. So, my problem is, I can't login to the mail servers via any client. It gives me a message saying the server mail.parahosting.net is not responding. And this recently happened after I moved to a brand new dedicated server. Is there a way for me to fix this problem?

Also, by default, it seems that we cannot accept/receive mail. Is there a way to change this to allow mail to be received/sent?
