Email Port Forwarding

Email port forwarding enables clientless access to popular thick client applications like Post Office Protocol (POP), Simple Mail Transfer Protocol (SMTP), Internet Message Access Protocol (IMAP), e-mail, online calendars, instant messaging, Telnet, SSH, and other client-initiated TCP applications via a small Java applet.
Smart tunneling allows Microsoft Windows users access to TCP applications without the prerequisite of administrative rights and allows VPN administrators to grant only approved applications access to internal resources.
