End a POP3 Session (Commit Deletions)

Demonstrates the Chilkat MailMan.Pop3EndSession method, which ends the current POP3 session by sending the QUIT command. Ending the session normally commits any messages that were marked for deletion during the session. This example begins a session and then ends it.

Background: POP3 deletion is deferred: DELE commands only mark messages during the session, and the server permanently removes them when the client sends QUIT to end the session cleanly. Pop3EndSession is that commit point. If a session is dropped without QUIT (see Pop3EndSessionNoQuit), the server rolls back the pending deletions and the messages remain.
