Don't use that, it's outdated and generates spam. Use Exiscan (
http://duncanthrax.net/exiscan-acl/ ) instead (it's part of
exim4-daemon-heavy if my understanding based on passive reading of stuff
about Debian is correct). Coupled with Exim 4's powerful ACL capabilities,
you can do everything Nigel's old system_filter does and *much more*. It's
also much more reliable at detecting "banned" file extensions and, more
importantly, does it without generating bounce mails yourself (which
inevitably ends up with you bouncing junk to innocent users).

Nigel, any chance of removing that old system filter from the site, or at
least putting a whopping great warning at the top of it? I have to report
with some sadness that in the current virus outbreak, bogus "bad
attachment" warnings generated by various versions of that old Exim filter
are outnumbering all other bogus virus warnings by something approaching
an order of magnitude here. Multiplied by the rest of the world, that must
be a lot of junk.
