Handling undelivered emails using Zend Mail

Question

I'm sending newsletter using Zend Mail. I have used setReturnPath() to put all undelivered mail notifications in one place.

And what now?

• How to get the list of addresses which were unreachable?
• How do I read and parse the returned notifications?
• How to know whether the mail returned because of non existing email or just quota exceeded?
• Which headers do I need to send and check?

This class may be helpful. Can determine whether the mail is a bounce and return a response code with description:
