Open an IMAP Mailbox Read-Only

Demonstrates the Chilkat Imap.ExamineMailbox method, which opens a mailbox as read-only. Use it instead of SelectMailbox when the application must not change message state, such as the \Seen flag. This example examines the Inbox.

Background: Reading a message can have a side effect: fetching its body normally sets the \Seen flag, marking it as read. ExamineMailbox corresponds to IMAP's EXAMINE command, which opens the mailbox in a read-only mode where no such changes are made — ideal for scanning, indexing, or backup tools that must leave the user's mailbox exactly as they left it.
