#  Connect to an SSH server and establish the SSH tunnel:

#  Authenticate with the SSH server via a login/password

#  be used exactly the same as usual, except all communications
#  are sent through the SSH tunnel.

#  this does not establish a direct connection with the IMAP
#  server.  It directs the SSH server to establish the connection.
