Explicitly Begin a POP3 Session

Demonstrates the Chilkat MailMan.Pop3BeginSession method, which explicitly begins a POP3 session by connecting to the POP3 server and authenticating using the current POP3 property settings. Calling it is optional. This example begins a session, performs a mailbox operation, and ends the session.

Background: Pop3BeginSession combines connecting and authenticating into one call. Chilkat does this automatically when a mailbox operation needs it, so the value of calling it explicitly is control: you open one session, perform several operations against it, and close it with Pop3EndSession — avoiding repeated connect/authenticate round trips and keeping deletion marks within a single, well-defined session.
