You can modify the above ruleset for this.
But this is prone to false positives - unless you have
1. inbound and outbound mailservers separated and apply this only to inbound
or
2. exempt trusted ips and authenticated users from this check
As for the message-id check, are you sure your user X isnt going to use
some other smtp server but from / message id are x@???, to
mail y@???, or support@???
