Delete a Bundle of POP3 Messages

Demonstrates the Chilkat MailMan.DeleteBundle method, which deletes POP3 messages using the UIDLs stored in the X-UIDL headers of the Email objects in an EmailBundle. An email without an X-UIDL header is skipped. This example fetches all messages and deletes them.

Background: DeleteBundle is the batch version of DeleteEmail: it marks every message in a downloaded bundle for deletion in one call. A typical "download and clear the mailbox" workflow is to fetch all messages, process them, then delete the whole bundle. Because a bundle can be filtered or built selectively, you can also delete just the subset you no longer need. The deletions commit when the POP3 session ends.

# Note: Explicitly connecting/authenticating is optional.  Chilkat MailMan automatically
# connects and authenticates -- using the property settings above -- whenever a server
# operation requires it.  Calling the explicit connect/authenticate methods can still be
# helpful to determine whether a failure occurs while connecting or while authenticating.
