Hello,
First of all thanks for all the replies you guys did on everything I have asked you all being a new BB user, so I installed 7.1 the other day and had to remove mark/unmark some stuff like I don't use so I came across this s/mime, and I didn't marked it first and then it was just 2 KB in size I was like must be some certificate or something so anyways I marked it and installed the OS
So now I went and it says about email encryption and its marked and unmarked for encryption, can someone really explain me what that is exactly and why would I ever need it and how important is that for Emails I send/receive.
