How many users use POP though? And how many users store / link<br>
valuable data in their POP account such as their facebook accounts,<br>
online banking, personal information and passwords for everything.<br>
They'd only need to get a username and password to a couple of users<br>
who have "Do not delete from server" set up on their clients to get<br>
everything.<br>
