title: Recommendations for email server with REST API?
body: <p>We are evaluating email servers and would appreciate recommendations.  Our basic requirements are:</p>
  
  <ul>
  <li>REST API - with option to also receive parsed messages as well as
  sending</li>
  <li>Spam and virus filtering</li>
  <li>Access to log files - to view bounce messages</li>
  <li>Deliverability - features to help avoid blacklisting and identify if
  emails are being blacklisted</li>
  </ul>
  
  <p>The use cases we envisage are broadly:</p>
  
  <ul>
  <li>Transactional emails</li>
  <li>Multiple independently managed email newsletters</li>
  <li>Multiple independently managed listservs</li>
  </ul>
  
  <p>Our preference would be for an open source application that we can host ourselves.  However, we are open to web apps as well.  Some of the options we are looking at are:</p>
  
  <ul>
  <li>Lyris ListManager - currently using this, but license is very expensive</li>
  <li>Mailman</li>
  <li>Sympa</li>
  <li>Postmark - <a href="http://www.postmarkapp.com" rel="nofollow">http://www.postmarkapp.com</a></li>
  <li>Mailgun - <a href="http://www.mailgun.net" rel="nofollow">http://www.mailgun.net</a></li>
  </ul>
  
  <p>Are there others you know of that we should consider?  If you have experience with using any of the above then that would also be great to hear about.</p>
  
  <p>Thanks!</p>
