Hm, if the message they see is really 'OK id=xxxxxxx' with a real
Exim-like queue ID (why the hell do you feel the need to obfuscate a
local queue ID, anyway?) then it's unlikely to have been generated
anywhere but your server.
If you search your logs for that specific ID, what do you see?
If you do a capture on *your* end, does it match what they see at their
end?
