MailTunnel creates a bidirectional virtual data path tunnelled in E-Mail messages. This can be useful for users behind restrictive firewalls that only allow Mail-Access (usually through a central mailhub). In a situation like the above, it's possible to use mailtunnel to tunnel anything from simple telnet sessions to SSH-PPP VPNs (practically anything that can be tunneled over TCP/IP) to a non-blocked system on the internet
