5.1 Security Considerations for Implementers

The PidNameExchangeJunkEmailMoveStamp property (section 2.2.1.2) is used to bypass content protection offered by client spam filters. If the valid junk email move stamp can be determined by an outside party, that party might discover a clever way to exploit the protocol such that untrusted and potentially malicious content could bypass protective filters.

Implement the procedure in section 3.2.4.1.2 in such a way that the value of the zero-based index 5 of the PidTagAdditionalRenEntryIds property (section 2.2.3.1) of the Inbox folder cannot be guessed.
