I came to expect file expansion everywhere in exim, to the point that I
actually read the specific doc for this variable :). But I was fooled by
the following:

2013-01-23 11:12:53 1TxxK8-0001A3-Vu failed to open
/etc/exim4/dkim_known_signers when checking
"/etc/exim4/dkim_known_signers": No such file or directory

It seems that the exim still tries to read the file nonetheless. When I
created the file, I basically expected exim to read it at this point.
