Note  Note
Normally, a MessageExpunged event will be emitted for each message that is expunged. However, if the IMAP server supports the QRESYNC extension and it has been enabled via the EnableQuickResync(CancellationToken) method, then the MessagesVanished event will be emitted rather than the MessageExpunged event.
