Like I said, I don't see any requirement for UIDVALIDITY to _grow_. It has to be _different_. > This means that a message that the client saw in A earlier may now > reappear in A with a different UID, but the UIDVALIDITY may be the same or > lower.

There should be no problem if it's lower, or the client is broken (or I've missed something in the specs).
