I don't have an explanation from your email why your local users do not
get the error message but I have just three remarks/questions:
1. I wonder whether it is wise to try and use Exim as a spamfilter. It
was not designed for that purpose.
2. Did you use exim -bh (or swaks with that option) to see how exim
handles the acl in question? My experience is that you can debug
most of the acl problems that way.
3. If you don't accept emails from mailer-daemons, how will your users
know when their emails could not be delivered by an external mta?
Regards
Johann

thou the person of any, but teachest the way of God

therefore unto Caesar the things which be Caesar's,
and unto God the things which be God's."
