What are the chances that all that org's e-mail is public by tomorrow morning?
Pretty good I'd think. Lots of hacker types around who read. Wouldn't take much to crack that box.
As a SE, if the contract fell my way, I'd have them completely offline for an upgrade on an emergency basis. Let the mail backup on the secondary- assuming his admin is smart enough to have done it right.
I'd bet dinner with a friend they are cracked by morning. If Trump had a decent IT staff they would not be in this condition.
