Seems like a DNS problem or something? Webmail works fine, old Email account under same domain works fine, just not new account under any domain. Checked settings, software, tried alternative configs (different Pop servers, the IP instead of the name, etc). Uninstalled and reinstalled Outlook, deleted and recreated the Pop account both in Outlook and on the hosting company, still nothing. Checked settings a hundred times of course. The environment is a Windows 2003 Small business Server, the clients are all Win XP Pro running DHCP with DNS and DHCP running on the server.

Any other ideas??? My hosting company and anyone else I talked to already thre w in the towel! Help! thanks
