exim4 problem

[R Kimber]

I have re-installed my system recently and I am now getting errors saying:-

2011-09-28 16:35:37 1R8wAb-00066H-Ok Expansion of
${lookup{${local_part}}lsearch{/etc/email-addresses}{$value}fail} failed
while rewriting: failed to open /etc/email-addresses for linear search: No
such file or directory.

Yet /etc/email-addresses *does* exist, and it has the same permissions as
the other exim files, namely:
-rw-r--r-- 1 root root
Does it need to be something else?

And it has the same contents as it had before the re-install, when I didn't
get these errors.  I'd be grateful for suggestions.

- Richard.
