Fixed

• IMAP:
  • APPEND and COPY/MOVE into another account's mailbox do not change the JMAP EmailDelivery state.
  • SEARCH RETURN with MIN or MAX alongside ALL returns only the minimum and maximum in ALL, and SAVE combined with MIN or MAX and ALL or COUNT saves only the minimum and maximum instead of every match.
• iTIP: Merging a received update does not copy the VTIMEZONE definitions it carries, so an occurrence moved by an external organizer can reference a TZID (for example W. Europe Standard Time) the stored event no longer defines, and Apple Calendar shows both the original and the moved occurrence.
• OAuth: Loopback redirect URIs without a path (for example http://127.0.0.1:45678) are not matched against registered loopback URIs on any port and are rejected by dynamic client registration.
• WebDAV: PROPFIND allprop returns DAV:current-user-principal, so Windows Explorer shows every file and folder under the account name.
