Sure.  Sorry, "disconnect ORBS" was not referred to you but to
your correspondent.
Keep in mind that your correspondent is now rejecting mail from
*any* site, not just yours, when it happens that the ORBS
DNS query is answered by some secondary server for the
(and not zone.
So at a certain point he will hopefully figure out.

Nothing is wrong at your site.  The guy running was giving 
secondary service to, NOT to That was
not resource-intensive, as was delegated
to other servers. 
After ORBS was closed, the delegations for were 
removed in the zone, but the list of secondary servers for in the org TLD servers remained unchanged.
So suddenly the secondaries of were flooded by DNS
packets from all over the world, relative to queries within  
The guy running the secondary at suddenly found himself
with the bandwidth saturated, he tried in vain to contact
Alan Brown to modify the servers, so he is now
adopting desperate measures to recover his bandwidth.

That someone would be the person in control of, Alan Brown.
His current address is at the end of .
Apparently it is difficult to reach him now.
