This is probably the same situation as FAQ 0833, but since you haven't
quoted the SMTP responses, I cannot be sure.
For a host to be an open relay, it must do TWO things:
(a) Accept mail for arbitrary addresses.
(b) Deliver that mail to its intended addresses.
Many people forget about (b).
Possibly what you are missing is receiver_verify.
