You seem to know about government IT stuff so I’ll ask
Back during the Bengazi affair I seem to remember Hillary using the word “cable”. that would be an archaic term for a telex or similar message that somehow made it into the age of the email. in my mind, the telex was replaced by the fax that was pretty much replaced by e mail.
one wonders if cables in the form of coded telex messages still exist in the State Department for very sensitive correspondence or if routine highly classified e mails are encrypted.
my thought is that Hillary just couldn’t be bothered with routine encryption and bypassed it and eventually may have just disregarded encryption at all.
A cable, I think is still being used in State adept terms, as “official” correspondence through official chAnnels. There used to be a system in DOD for messages just like in DOS, but now a days I think it is all email, just through official email addresses. By the way, a “cable” would also be written clearly and consisly, for formal than a standard email.
