This is serious, what the hell is going on with your servers? I have thousands of saved emails in my inbox that have apparently gone away or been deleted in the last 24 hours and the IMAP continues to plague all users it appears with long timeouts and denials. I am actively looking for a new email host if this cannot be resolved and the missing mail restored. i want and answer within 36 hours please!

Sincerely
