No one hacked anyone's emails. People are intuitively stupid and forget to log off of public computers, let other people borrow their email accounts, or put their passwords on sticky-notes which they put on the side of their monitor. In fact, I had a teacher who put their password on a sticky-note, and someone logged on their computer in the middle of the weekend and scheduled about 40 pages of research to be printed, which were printed on Monday when the staff started up the printer.
It kind of annoyed me because it used up all the ink and I wasn't able to print out anything for a week since a new cartridge had to be special ordered.
Another problem is people setting the admin password to their server as the same password as their email. And their forum accounts and bank accounts.
