All e-mails from INBOX of all accounts just disappeared

The Dreamhost mail server works very poorly. The users permanently complain that server is frequently down, emails are lost. Yesterday (2 November, 2012) all e-mails from INBOX of all accounts just disappeared.

I apologize for the frustration.
