Explicitly Connect to the POP3 Server

Demonstrates the Chilkat MailMan.Pop3Connect method, which explicitly connects to the POP3 server. If SSL/TLS is required by the current property settings, the secure TLS channel is established as part of connecting. This example opens the connection.

Background: Pop3Connect performs just the connect (and TLS handshake) step, without authenticating. Separating it from Pop3Authenticate gives explicit control over the session lifecycle and makes it easy to tell a connection failure apart from a login failure. For routine mailbox operations you don't need it — methods like CheckMail connect automatically.
