Fetch the Flags Set on an IMAP Message

Demonstrates the Chilkat Imap.FetchFlags method, which returns the flags currently set on a single message as a space-separated string. The first argument is the message ID and the second (bUid) selects UID vs sequence number. This example fetches and prints the flags for one message identified by UID.

Background: The returned string is the server's current flag list for the message, such as \Seen \Flagged. This is a quick way to check a single message's state — for example, to decide whether it still needs processing — without downloading the message itself. To read the same information from a message you already have as an Email object, use GetMailFlag instead.
