title: SmtpClient.send method threw "Failure sending mail" exception
body: <p>My mail program works on 2 boxes but throws "Failure sending mail" exception on the other box. This exception message is not very descriptive. Is there a way to dump the exception trace for the ease of debugging as discussed in <a href="https://stackoverflow.com/questions/2209617/smtpclient-failure-sending-mail">here</a>?</p>
  
  <p>Thanks.</p>
