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?

You must not have a roaming staff or are willing to keep telcos wealthy.

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