Bounced Email Pipe to PHP file with cpanel

I need help with the basic set up in cPanel to have bounced emails piped to a PHP file which will then parse the emails into the different categories for why it bounced (bad address, mailbox full, blocked/spam, etc.) I have set up a simple page to send email to test the different scenarios. I need the basic pipe to the PHP file to work (ensure the right shebang is set up, end of line returns are ok, chmod ok on the file and directory, etc.) Then the PHP file itself needs to parse the email from, subject, body, etc. and then determine each of the various scenarios: - Bad email address - Mailbox full - Blocked by spam filter - Temporary/out of office responder - Other (a regular incoming email) (and add any other standard categories). No code needs to be created to take any action, but just the logic created to identify each of the scenarios/cases. This is probably a very quick 1 hour job for anyone familiar with the set up, but message me if you feel it will take longer. I can provide FTP access to the files, as well as cPanel login.
