Unsubscribe from an IMAP Mailbox

Demonstrates the Chilkat Imap.Unsubscribe method, which removes the subscription to a mailbox. The mailbox itself and its messages are not deleted. This example unsubscribes from a mailbox.

Background: Unsubscribing simply drops a mailbox from the account's subscription list, so clients that show only subscribed folders will stop displaying it — the folder and everything in it remain on the server untouched. This is the counterpart to Subscribe, and is how you declutter a mailbox listing without deleting anything (deleting a folder is DeleteMailbox).
