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
relay?

POP-Before-SMTP is good. SMTP AUTH is better. Solves the problem quite nicely.
