This is really less a diary and more a question to the vastly more computer literate DKos community at large.
I've been reading about the missing emails at the RNC, and I am curious, how does an email disappear?
Sure, if I click "delete" after selecting an email it is "deleted." But doesn't a copy of it remain on the server I used to send it? Doesn't a copy remain on the server to which it was sent? I always just assumed these things were compressed and stored in the event they ever needed to be retrieved.
Does anyone know how these things generally work?
