Hi,

Allow me to ask why this is happening:

I am using the Exim system_filter.

While running with Exim-3.22 it used to give a message like (1) below when
it catches one of those files.
Now with Exim-3.31 (nothing changed in the configure file) it gives a
message like (2) below. Exim on FreeBSD compiled from tarball.

Thanks.
