/**
 * Complex constructor.
 * 
 * @param authHandlerFact
 *            the {@link AuthenticationHandlerFactory} which performs
 *            authentication in the SMTP AUTH command. If null,
 *            authentication is not supported. Note that setting an
 *            authentication handler does not enforce authentication, it
 *            only makes authentication possible. Enforcing authentication
 *            is the responsibility of the client application, which usually
 *            enforces it only selectively. Use
 *            {@link Session#isAuthenticated} to check whether the client
 *            was authenticated in the session.
 * @param executorService
 *            the ExecutorService which will handle client connections, one
 *            task per connection. The SMTPServer will shut down this
 *            ExecutorService when the SMTPServer itself stops. If null, a
 *            default one is created by
 *            {@link Executors#newCachedThreadPool()}.
