PHP Script for Email validation and verification

I need a script that can check a large number of email addresses and provide list of valid and working email addresses, email addresses that are bounced and email addresses that were not allowed to check for some reason (need to specify the reason). Need to be able to stop the script in the middle if required and also if it shows how much data was sent & received, it'd be great. 1. Saving to CSV, txt or Excel format is a must. 2. Ability to stop the process in-between. Should be able to restart also. 3. Great if you can show bandwidth usage (sent and received data) More discussion through PM. Happy bidding.
