Remember anti virus software ONLY protects against KNOWN viruses.
tomorrow's modified KLEZ virus will probably not be caught by today's
anti-virus code, and so your anti virus installation relies on
 1.  The vendor updating their software
 2.  The system admin installing (or having an automated process) to
     update the software.


The BIG bonus with the system_filter.exim file is that it is simple
and has stopped numereous viruses before anti virus vendors have
realised that there s a new virus on the rounds.

It would be great to know why the system_filter.exim file
http://www.exim.org/system_filter.exim
is no longer being maintained, as numereous of use Exim users have
benefited from its simple and effective screening.


Cheers,

Douglas.
