Ah. I see. Well nearly; I checked if the file was readable, of course,
in fact I made sure it was publicly accessible, i.e. it has
ls -l /usr/local/etc/mail.all
-rw-rw-r-- 1 root sys 235 Jan 26 11:00
/usr/local/etc/mail.all
However, I now suddenly realised that I have
# su - exim
UX:su: ERROR: No shell
- maybe this is the real problem? Is denying normal login for "exim" in
this manner generally a bad idea? (I should perhaps point out here that
I've upgraded from a version that was built by someone else, and
apparently configured to run as root rather than exim.)

OK.
The user setup is actually there mainly with pipes in mind, i.e.
addresses that are aliased to "|<some command>"
