This kind of problem is often caused by DNS servers getting out of step.
But not, I suspect, this time... see below ...

This is a reject during recipient verification.

This is a successful delivery.

Therefore, your routers are behaving differently during verification and
delivery. Check all the "verify" options on your routers. Check the
address with -bt (as a delivery address) and -bv (as a verification
address).
