Hi Marc.

I just checked, I did not manually set local_scan to anything, I found out
that it was set by the package sa-exim, which dropped the
15_sa-exim_plugin_path file in /etc/exim4/conf.d/main/ and the sa-exim.conf
file in /etc/exim4. I just checked that removing sa-exim fixes my problem,
and reinstalling it reintroduces it. So I guess this bug should be moved
from exim4 to sa-exim, even if fixing it will probably still require some
help from the exim4 maintainer(s).

The sa-exim package though appears to have not been upgraded for a long
time, so something else broke it.  Maybe some exim interface changed and
sa-exim needs to be recompiled against it?  Or some other recent
configuration change?
