Looks like this is http://files.directadmin.com/services/system_filter.exim
based originally on something Nigel wrote, but which was never distributed as
part of Exim.

I remember seeing this and using something like it, many years ago, but I think
that it was always a hack to try to get "something" working and, impressive
demonstration that it was, it became obsolete with the introduction of the
content scanning functionality into Exim. What the filter does can be done
more cleanly directly in the Exim configuration via ACL rules using the content
scanning functionality.

So this system filter should be considered an obsolete example of how things
could be made to work in very old Exim, based upon something which Nigel posted
to the mailing-lists way back when (I _believe_ before he had commit access,
but could be wrong), but which is continuing to surprise when it resurfaces.
If it was automatically installed as part of an Exim package for some
distribution, please talk with your OS vendor.

I encourage you to check out the
http://www.exim.org/exim-html-current/doc/html/spec_html/ch-content_scanning_at_acl_time.html
link which Nigel provided; in particular, "$mime_filename" and
"$mime_decoded_filename" if you want to look at the full filename.
