#  Anything unlocks the component and begins a fully-functional 30-day trial.
$success = $imap->UnlockComponent("Anything for 30-day trial");

    exit;

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

#  The SSH hostname may be a hostname or an
#  IP address, such as "192.168.1.108".
#  The port is typically 22 (the standard port for SSH).

#  Authenticate with the SSH server via a login/password
#  or with a public key.
#  This example demonstrates SSH password authentication.
#  Note: This is not authenticating with the IMAP server, it is
#  for authenticating with the SSH server, which is separate.

    exit;
}

#  OK, the SSH tunnel is setup.  The IMAP component may
#  be used exactly the same as usual, except all communications
#  are sent through the SSH tunnel.

#  Connect to an IMAP server via the SSH tunnel.
#  Because the SSH tunnel has been previously setup,
#  this does not establish a direct connection with the IMAP
#  server.  It directs the SSH server to establish the connection.
$success = $imap->Connect("mail.chilkatsoft.com");
if ($success != 1) {
    print $imap->lastErrorText() . "\n";

#  Authenticate with the IMAP server via the SSH tunnel.

# messageSet is a CkMessageSet

#  Fetch the emails into a bundle object:

# bundle is a CkEmailBundle
$bundle = $imap->FetchBundle($messageSet);

#  Loop over the bundle and display the FROM and SUBJECT of each.
