Can someone please help me resolve this issue? I'm willing to pay if required to get this back up! I've been down since 11PM Saturday.

could you please post the output of

dovecot -n

Are any other errors logged in mail.err or mail.info? Have you compiled Dovecot yourself or have you used a binary package?
