I would have expected this file to have group Debian-exim (or mail), not
saned which is normally used for a scanner server.

Please check the access and ownership of /etc/eximr4 and files in it.

  ls -ld /etc/eximr4        # for the directory itself
  ls -l /etc/eximr4         # for the files in it


Then use the chgrp and chmod utilities to fix things up.

This is probably a very Bad Thing. Everyone can now read your password
file :-o

Only if that user can also read the content of the directory in the
first place. For that it needs r-x on the directory.

Hope this helps,
