body: <p>Is it possible to send mail asycronously using PHP while giving live user feedback on delivery?</p>
  
  <p>I have recenty written a small app for our company's intranet for sending formatted emails to customers. The interface is quite clean and only requires the input of a job number, it then builds and sends the mail. The mail, while being built, obtains a number of attachments from another server and everything is automated. The library used is <a href="http://phpmailer.worxware.com/" rel="nofollow noreferrer">PHPMailer</a>.</p>
  
  <p>Is there a way, using other technologies, possibly, but still using PHP as the main language, to show progress of the mails being sent? I have coded robust error checking to check if the mail was actually sent, etc. but i am missing a way of giving users the visual clue of actually delivering the mail to the server via a progress bar, etc.</p>
  
  <p>Is this possible using PHP and something like Ajax? How would you determine the progress of the mail in transit?</p>
