Well, in a sense it does, but perhaps not in the sense you hoped. The mailbox name + UIDVALIDITY certainly identifies a unique instance in that it won't be duplicated by some other mailbox. You can rely upon that.
But you can't assume that this identification is static; although a mail store which does not maintain UIDVALIDITY for mailboxes with messages can be considered defective (although not "non-compliant"). Some of the formats supported by UW imapd are defective in this way, although the major formats are not.
The default setting of UW imapd avoids changing UIDVALIDITY even with traditional UNIX mailbox format; but there isn't much that can be done if the site (or user) insists (deliberately or inadvertantly) upon sabotaging the mechanism that is used.
