Exchange 2000 Pop3 connectors

I’ve just recently installed Ms Exchange 2000, and since it’s not the Sbs edition i’m looking for a good Pop3 connector. I’ve tried one called eXchange POP3, but it a seperate program. Is there a connector integrated with Exchange 2000 like the Sbs one? What pop3 connectors would you advice me to use/try?
Thank you.
