[Imc-tech] more email stuff

[Arun Bhalla]

On the topic of email management, here are a couple other tools that have
been helpful for me.

Rules Du Jour - http://www.exit0.us/index.php/RulesDuJour
It's a bash script that automatically downloads and installs new
custom SpamAssassin rulesets which get published every so often.
I use all of the recommended rulesets.  The more effective rules
seem to be those pertaining to drugs or blacklisted IPs.

ClamAV + ClamAssassin - clamav.sourceforge.net
ClamAV is an open-source virus scanner.  Its virus database is updated
automatically care of the daemon freshclam.  ClamAV is more oriented
for files than emails, so I use ClamAssassin, which is a very simple
shell script that functions as a procmail filter.  ClamAssassin functions
a lot like SpamAssassin in that it adds headers to emails, but all of
the intelligence lies in ClamAV.  ClamAV is written in C and seems to
be very lightweight.  There might be some other 3rd-party software to
interface between Postfix and ClamAV.

I filter email through ClamAssassin before SpamAssassin, expecting that
email viruses need not be checked for spam.  In the past few hours, however,
I've only received 3 emails containing viruses -- perhaps it's a light
day.  One virus was received for a mailing list, so virus-scanning might
help in reducing network traffic.
