pop email script

Hallo,

Ik heb een pop mail script op internet gevonden. Deze ben ik nu aan het aanpassen, maar ik zit met 1 punt waar ik niet uit kom. Nu laat het script namelijk zien hoeveel berichten er in de inbox staan, maar ik wil eigenlijk alleen het aantal met een bepaald onderwerp zien staan, is dit mogelijk?

hier de 2 scripts die ervoor zijn.

pop.php

<?php
/*
Really generic POP class, instead of using IMAP/SOCKETS
