[O] [OT] s/mime / mail encryption

[Marcelo de Moraes Serpa]

A bit off topic but related I think...

I've started using gpg to encrypt org-mode entries and it's amazing. I then started to realize that I wasn't paying enough attention to security of my own sensitive data. Scan of documents spread around without encryption (also looking for a pragmatic way to encrypt whole files in OSX) and specially email of sensitive data and documents. 

I've then found out about S/MIME? I don't see it as widespread, I only found geeky tutorials (some are quite comprehesive) but nothing really mainstream. I also found a bit of material talking about encryption of emails with gpg. 

Do you guys ever encrypt your emails? I must say I never did, but it doesn't sound bad for sensitive data, and if you have a business and or need to deal with services that require your business or personal documents (or any other sensitive data for that matter) I think that it could be a good choice.

What do you think?
