That's a really sticky question. The only real way is to have PHP monitor an inbox to check for "undeliverable message" notices you might get back. If you're really wanting to go forward with it, look into POP3 connectors for PHP. Like this: http://pecl.php.net/package/POP3

if (strpos(strtolower($subject), 'undeliverable') !== false){
    //do whatever you want with the address that couldn't be reached
}

You technically wouldn't need a compiled PHP extension for POP3 (especially if you're new to PHP)... you could connect and read messages by opening a socket and speaking mail server: http://www.adamsinfo.com/a-rudimentary-php-pop3-example/
