Hi partly diskussed in: https://bugzilla.mozilla.org/show_bug.cgi?id=365651#c4 snip --- ftp://ftp.rfc-editor.org/in-notes/rfc3501.txt 6.3.5. RENAME Command The value of the highest-used unique identifier of the old mailbox name MUST be preserved so that a new mailbox created with the same name will not reuse the identifiers of the former incarnation, UNLESS the new incarnation has a different unique identifier validity value. See the description of the UID command for more detail. If IMAP server returns same "unique identifier validity value" after rename, IMAP server MUST preserve "highest-used unique identifier". snip --- the problem is, where to store the old "highest-used unique identifier" for the same mailboxname, if reused ?? the logical solution is to generate new uidvalidity for renamed mailbox, that guarantees, that in case of existing previous mailbox with the same name, that the change to other content is recognized ..
