When you enable IMAP access in Gmail the [imap]/Drafts, [imap]/Sent and [imap]/Trash labels are created. How do these labels function given that each IMAP client can potentially implement their local <--> server folder mapping in different ways?
Taking these label/folder names at face value I'd assume that they map to the client's Drafts, Sent and Trash folders respectively. But I haven't found this to be the case at all as Thunderbird handles folder mapping one way, the iPhone 4 IMAP client another, Outlook yet another and so on.
At the end of the day I want what every IMAP user wants which is their sent messages to show up in whatever the server's sent folder is called, same for trash and drafts.
