/// 2. Call login() or login(hostname).
/// 3. Call startTLS() to switch to a secure connection.
/// Check the return value to see if a secure connection
/// has actually been established (not all servers may
/// support STARTTLS).
/// 4. Call any of the login() methods to securely authenticate
/// with a username and password.
/// 5. Send the message(s).
