Secure Communication with Stunnel
"One of Stunnel's most common uses is encrypting communications between POP or IMAP mail servers and e-mail clients. Both of these protocols require users to authenticate themselves with a username and a password. In the majority of cases, these usernames and passwords are the same ones as they would use for logging into the machine locally or remotely via SSH. Without using Stunnel to encrypt this data, anyone intercepting the transmission could now log into your server and gain elevated privileges much easier than a local exploit would require."
