PHP SCRIPT : Collect Bounce Emails, make then available in CSV or Text Format and remove then from original list

This is a very quick project (1) Lets say when i send Bulk emails, some bounce back (2) This PHP script will let me download either in CSV or Notepad format all the emails ensuring previous downloaded emails are not captured again (3) With this list in hand, I can now REMOVE these Bounced Emails From the Master List that i used to send emails at the first time Thats all.
