Sorry, that is incorrect. Postfix features of the form "reject_<predicate>" cannot promise that a recipient (or sender, client, helo) will be accepted when their predicate is false. They can't promise that, because there may be a different "reject_<predicate>" instance whose predicate is true. The only thing that a "reject_<predicate>" feature can promise is that it will reject a recipient (or sender, etc) when the predicate is true. As that is why the text for reject_unlisted_recipient describes under what conditions it will reject, not accept, a recipient. Wietse
