Subscribe to an IMAP Mailbox

See more IMAP Examples

Demonstrates the Chilkat Imap.Subscribe method, which subscribes the authenticated IMAP account to a mailbox. Subscription controls which mailboxes are returned by subscribed-mailbox listings. This example subscribes to a mailbox.

Background: An account can have many mailboxes, but a user often cares about only some of them. IMAP's subscription list is that curated set: mail clients typically show subscribed folders by default and hide the rest. Subscribing does not create or change a mailbox — it only adds it to the "show me this one" list (retrieved with a subscribed-only listing). Unsubscribe removes it from that list.
