I've just looked at the IMAP4 RFC which isn't as impenetrable as some. It *seems* from that that the SUBSCRIBE/UNSUBSCRIBE commands are really intended for newsgroup use, all the examples refer to newsgroups, but it isn't explicitly spelt out. It doesn't say anywhere what happens when a mailbox is subscribed to, the only difference it makes is that a subscribed mailbox will be listed by the LSUB command whereas an unsubscribed one won't.
