Delete a POP3 Message by UIDL

Demonstrates the Chilkat MailMan.DeleteByUidl method, which marks the POP3 message identified by a UIDL for deletion. UIDLs are preferred over message numbers because they remain stable across sessions while the message stays in the mailbox. This example marks a message for deletion by its UIDL.

Background: Because a UIDL uniquely and persistently identifies a message, deleting by UIDL is the reliable way to remove exactly the message you intend — even if the mailbox changed since you last looked. As with all POP3 deletion, the message is only marked during the session and is actually removed when the session ends normally (the QUIT command).

;  Note: Explicitly connecting/authenticating is optional.  Chilkat MailMan automatically

;  operation requires it.  Calling the explicit connect/authenticate methods can still be
;  helpful to determine whether a failure occurs while connecting or while authenticating.
