Verify POP3 Login (Connect and Authenticate)

Demonstrates the Chilkat MailMan.VerifyPopLogin method, which tests whether Chilkat can connect to the configured POP3 server and successfully log in using the current POP3 authentication settings. This example configures the POP3 host and credentials and verifies login.

Background: POP3 login is the USER/PASS (or APOP/SASL) exchange that follows connecting. VerifyPopLogin performs the full round trip — connect, TLS, and authenticate — making it the go-to preflight check for validating a mailbox's credentials. A false result after VerifyPopConnection succeeds isolates the problem to the username or password.
