Authenticate an IMAP SSH Tunnel with a Password

See more IMAP Examples

Demonstrates the Chilkat Imap.SshAuthenticatePw method, which authenticates the SSH tunnel using a username and password. The first argument is the SSH login name and the second is the SSH password. Call SshOpenTunnel first; after SSH authentication succeeds, connect and log in to IMAP.

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
