We may be talking at cross purposes. I believe I understand the role of
UIDs perfectly and appreciate their enormous value in the overall IMAP
design. I was taking issue only with the question of exactly when they
must be assigned. I cannot see that it matters if a message is not
assigned an IMAP UID if IMAP never sees that message.
On the other hand, there are so many ways to interpret things that this may
all be moot. My IMAP server assigns UIDs to messages that don't have them
when it opens a folder. I tend to think of a message being added to a
folder when a transport provider or client puts it there. But we could say
that a "MAPI folder" virtually becomes an "IMAP folder" when and only when
the server opens it and, in that virtual sense, new messages are added and
assigned UIDs only at that point. In which case I am following this part
of the spec to the letter.
