title: How to handle mail delivery errors with PHP
body: <p>I am building a symfony module for sending newsletters. the idea is to build a queue list of adreeses to receice the mail and then ,with a cron job, send let's say 50 at a time.</p>
  
  <p>What i don't now how to do is to read the Mail Delivery reports that are sent back by the server when an email adress doesn't exist or the mail is full. The idea is to store these error reports an clean the adress list.</p>
  
  <p>Any ideea how to implement that?</p>
