Delete a Set of POP3 Messages by UIDL

Demonstrates the Chilkat MailMan.DeleteUidlSet method, which marks the POP3 messages whose UIDLs are listed in a StringTable for deletion. Chilkat processes the UIDL set and sends a DELE command for each located message. This example deletes two messages by UIDL.

Background: When you already know exactly which messages to remove — by their stable UIDLs — DeleteUidlSet deletes them all in one call without first downloading them. It is the efficient counterpart to fetching-then-deleting: for example, after processing messages elsewhere, hand back just their UIDLs to clear them. The deletions are committed when the POP3 session ends (unless ImmediateDelete is set).

;  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.
