http://www.ctyme.com/filter.txt - as a basis. He doesn't bounce the mails but you
can change the rules to do that if you're that brave ;-)

if $message_body contains "password" then finish endif
if $h_subject: contains "password" then finish endif
something alog those lines but I bet if your users have shell access then
better let them run their own filter via the .forward
Below is a snippet of what was posted to this list sometimes back..
wash$ cat .forward
# Exim filter
# Error trapping
if error_message then finish endif
if $h_subject: contains "Viagra" # Real men don<92>t need it
or ($h_Subject: matches \\\$\\\$+) # No dollars for me
or $h_subject: contains "Card" # Credit card scams
or $h_subject: contains "Weight loss Offer" # Fat is a sign of maturity
or $h_subject: contains "Lowest Mortgage Rates" # Got my mortgage
or $h_subject: contains "Free Pics" # Avoid RSI today

You mean clues like those above?? And if you can get exim-$VERSION.tar.gz
from the ftp sites and do a tar xzf on it, you'll find in the docs directory
a file called filter.txt which explains howto use the filter..
