There's a msg hdr property called something like "message-offset" that's used instead of the msgKey as the offset into the local folder, by the berkeley mailbox store. The
msgKey is used for backwards compatibility if there is no message-offset. Are you saying the message-offset is never used, or sometimes not used?
