(Classic ASP) IMAP over Multiple Hop SSHDemonstrates how to read IMAP email (using TCP or TLS) tunneled through mulitple-hop SSH. The scheme looks like this: Application => ServerSSH1 => ServerSSH2 => IMAPServer The ConnectThroughSsh and UseSsh methods are added in Chilkat version 9.5.0.55 to accomplish this task.
