Most clients cache mails based on UIDVALIDITY and UID, so if UIDVALIDITY changes, it re-downloads all mails. If just UIDs change, then it's handled exactly the same way as if all messages just got expunged and added back, so again it'll re-download them.
You mean, one single UID differ between the client's cache and what the server sends and the whole mailbox is fetched again ?
So UIDVALIDITY is just basically the "instance number" of a mailbox, right ?
