It all depends on how you start qpopper. If you use xinetd, you can specify different configurations and command lines for different interfaces and ports. So you'd run a non-TLS APOP-capable qpopper on your internal interface at the pop3 port, and a SSL-only qpopper on the pop3s port on the external interface.
