title: Does SmtpClient.Timeout Property work for asyncronous calls?
body: <p>In the <a href="https://msdn.microsoft.com/en-us/library/system.net.mail.smtpclient.timeout(v=vs.110).aspx" rel="nofollow noreferrer">docs</a>  it says <code>Gets or sets a value that specifies the amount of time after which a synchronous Send call times out.</code></p>
  
  <p>Does this not work for asynchronous calls?, sometimes my calls are taking far too long and I need a max timeout for them. How can I achieve this with async?</p>
