What is SSL and why should I use that?
SSL (secure sockets layer) is a method of encrypting your information when you read your email with a web browser. This ensures that anyone maliciously ‘eavesdropping’ on your network connection cannot read your email. Most users do not need this, but it is a nice added security feature. Some people running behind a firewall are required to use this, or your firewall will block access to your email.
