Yes, reject_unverified_sender is the problem. The MX for
unfccc.int doesn't like your address probe.
You may possibly be able to fix this by adjusting the value of
address_verify_sender; some misconfigured systems don't accept
mail from "postmaster" or "<>"
http://www.postfix.org/postconf.5.html#address_verify_sender
If that doesn't help, you will need to add the client to a
whitelist, or stop using reject_unverified_sender.
