  // Some SMTP servers do not actually send the email until 
  // the connection is closed.  In these cases, it is necessary to
  // call CloseSmtpConnection for the mail to be  sent.  
  // Most SMTP servers send the email immediately, and it is 
  // not required to close the connection.  We'll close it here
  // for the example:
  try {
    mailman.closeSmtpConnection();
  } on ChilkatException {
