Every FEDGOV employee that has a computer has to take training every year in order to get a password to access their agencies network.
This training specifically states that personal e-mail is NOT to be used for government business.
In addition to that, DHS has of a few months ago blocked access to ANY personal e-mail on their computers (Yahoo, G-mail, etc.)
That the goddamned SOS was using non-secure e-mail is preposterous, and only an effin Clinton would have the audacity to do it.
