That is not the new feature. Exim already does that by default and it
can be configured to hide the detail.
The problem I have is that the information is not logged and is not
available in a variable so I can't include it with other messages.
I also can't handle the "defer" outcome in an ACL without losing the
automatic SMTP-level responses that Exim does have.
