Server Error. Virtualmin server down

We are unable to connect to our mail server. Keep getting error:

Entourage cannot find the server. Verify the server information is entered correctly in the Account Settings, and that your DNS settings in the Network pane of System Preferences are correct.

All the settings are correct and we can not log into the server via web either.

This is very important to our business that the email system is working. Please contact us ASAP to get this resolved.

We are unable to access the console at all.

Thank you. Raymond Bryant
