I'm really not sure you want to do that. With my 
server-implementor-hat on, I wouldn't want to code it, and with my 
client-author-hat on, I wouldn't want to use it.

All you need do is know that changes have happened - you don't need 
to know what. NOTIFY handles this by having the server send a STATUS 
(EXISTS HIGHESTMODSEQ), which indicates to the client that flag 
changes have happened, and/or new messages have been delivered.

The client then uses QRESYNC to select and synchronize the mailbox as 
and when needed. It's useful to know, however, that SELECTing the 
mailbox and synchronizing will not yield any information, so it's 
more useful to eliminate this round trip.

If a client needs to actively and closely monitor multiple mailboxes, 
it simply uses multiple connections. If a client is monitoring all 
mailboxes on the server, it's probably broken anyway.

You'd be better off discussing this in the Lemonade WG, however.

Dave.
