headers: return path is <nobody@???>
Oh dear. That isn't a failure of sender_verify; it is a failure of
headers_sender_verify. Unfortunately, there is a present no way of
setting up any exceptions to it.
[Actually, I note that <nobody@???> is in fact a perfectly
acceptable sender address, so sender_verify would work on it.]

You could just turn off headers_sender_verify. This would accept
messages with valid senders in the envelope, but not check the headers,
except in the case of error messages (which have an empty sender in the
envelope).
If that is not acceptable, then the only alternative is to find some
cunning rewriting scheme for one of the headers that comes from
iee.org.uk.
