Email issues- Server admin

My HP 8020n tower Vista computer was recently stalled, and unable to reboot.I reset to factory settings, and loaded the MS SP1 and 2 (Beta), and other stuff.. Performance wise its good. Now with my outlook, i have problems receiving incoming mail from the server. It seems everything is set up correctly.. (It was working before). I have sites hosted at [login to view URL] on a virtual dedicated server. I have a mail forwarder on these sites and I receive the "test message" from outlook at my hotmail account. I checked with ISP and all is fine, with Godaddy server (Some blogs say i have to reset my email SMPT to MSN SMTP? or ??), i can send out mail but cannot receive. I have a linksys router. I have disabled all sort sorts of firewall, but no luck. I tried installing mozilla bird, it can send out emails but cannot receive " Connections to server [login to view URL] time out". I am looking for someone with experience to check my server setting and help me walk through the problem.
