I'm not sure I understand this logic:

1.) They test positive for orbs... so they ARE an open relay
2.) That system is using MAPS, which means that there is some subset 
of systems the open relay itself rejects mail from

Somehow that means that non-MAPS-listed sources (of which there are 
many) are somehow magically restricted from relaying through the open
