If you want to be RFC-compliant you shouldn't.
Message-ID is not a mandatory header, so you cannot rely upon it
being present. For a while I was doing something similar and found
too many false rejections to use it, even though most rejections were
spam not all of them were.
On the other hand I've had good success rejecting messages with
no Date header - as that MUST be present...
