It depend......if you run Exchange only for basic email server(POP3 and SMTP) thats all the port you should open. But if you run a complete Exchange server which mean beside POP3/SMTP, also all its workgroup function like journal, contacts list, public folders, then there will be few more ports you should open. But for a better security, normally we don't allow external people to access the workgroup function of Exchange only for POP3 and SMTP. If they still want to access all function, better to go through VPN first at then access Exchange workgroup function.
