At present the greylist contains one record per recipient. I think this
behaviour would not need to change.

Yes, per recipient. No need to change here neither.

If you think of it as stages, a racl whitelist only means, that the
sender can step to the data stage, without further investigation at the
rcpt to stage.

At the moment a whitelisted recipient also becomes blacklisted if an
according dacl entry exists. Finally this is a configuration issue and
the mta administrator must be aware that data acls can overwrite
recipient whitelists.

The pro is obvious. If it was possible to greylist at the data stage,
many additional spam checks on the message body were possible.
