Answer 1

Take a look at php's imap extension module. It can access both pop3 and imap accounts.

If and how you can start a script when an email is delivered to an inbox depends on your local mailing system. E.g. with qmail you can use a command line in .qmail. You might want to ask on ServerFault how this exactly works and how it is configured (and where; afaik .qmail is not the only place where you can add a command line).
