bool success = false;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Imap imap = new Chilkat.Imap();

// Use TLS

// Login
success = imap.Login("myLogin","myPassword");

// First examine the already subscribed mailboxes.
