title: deliver_later with no retry
body: <p>How do I disable retries with activeMailer and <code>deliver_later</code>?</p>
  
  <p>I recently ran across an issue where one of my mailer methods was failing silently due to a syntax error in a view.  We were using <code>deliver_later</code> to send messages</p>
  
  <p>When it was finally discovered and fixed, all the old messages that had been failing were re-attempted and then delivered.  These were time-sensitive messages and should not have been retried.</p>
  
  <p>I can not seem to find any way to do something like <code>.deliver_later(retry: false)</code>  Would using <code>deliver_now</code> solve this problem?</p>
  
  <p>I am using delayed_job as my message queue.</p>
