I'm an IMAP client and my user has clicked the delete-message button. Accordingly, I've sent a command to make the change and I'm waiting for the response from the server.

Oh no! Before the response came back, my connection to the server died. I don't know if my request arrived and was accepted.

Time passed and I've just now managed to reconnect. I need to know if the delete happened or not.

Check to see if the \Deleted flag was added to the message.

Which message? I have a UID that's no longer valid and the message IDs have all moved.
