A couple of days ago Google started pushing encryption for e-mail. No, we are not talking about the typical https connection required for Gmail. We are talking about actually encryption of email as it moves from server to server using TLS (Transport Layer Security). In simplest terms this method creates connections between servers using a secure tunnel to each other for the purposes of transmitting the message. Once the message has been passed to the destination server the tunnel closes. However, despite the length of time TLS has been around not many companies use.
