End a POP3 Session Without Committing Deletions

Demonstrates the Chilkat MailMan.Pop3EndSessionNoQuit method, which closes the POP3 connection without sending the QUIT command. Pending deletion marks are not committed — messages marked with DELE during the session remain in the mailbox. This example marks a message for deletion and then abandons the session so the deletion does not take effect.

Background: POP3's deferred-deletion model effectively gives you a transaction: marks made with DELE are only applied when the session ends with QUIT. Ending without QUIT is therefore a rollback — useful if an error occurs mid-processing and you'd rather leave the mailbox untouched than risk deleting messages you failed to handle. Use Pop3EndSession when you do want the deletions committed.
