Fetch a Single IMAP Message into an Email Object

Demonstrates the Chilkat Imap.FetchEmail method, which downloads one message (or its headers) into an Email object. The arguments are headerOnly, the message id, bUid (UID vs sequence number), and the Email that receives the message. This example fetches message 1 in full and reads its subject and from.

Background: FetchEmail parses a downloaded message into a fully navigable Email object, giving you its subject, sender, body, and attachments. Passing headerOnly = true downloads just the headers — a fast way to build a message-list preview — after which you can fetch the full message on demand. Because a mailbox must be selected first, and fetching a full message can set the \Seen flag, use ExamineMailbox instead of SelectMailbox when you must not change read state.
