Verify Connectivity to the POP3 Server

Demonstrates the Chilkat MailMan.VerifyPopConnection method, which tests whether a TCP/IP connection can be established with the configured POP3 server. It verifies connectivity only — it does not authenticate. This example configures the POP3 host and checks whether it can be reached.

Background: This is the POP3 counterpart to VerifySmtpConnection. It answers the first diagnostic question — can the client reach the POP3 server on the configured host and port and complete the TLS handshake? A failure here indicates a network, firewall, DNS, port, or certificate problem rather than a credentials issue, which VerifyPopLogin checks next.
