If you want to think a bit outside the box and if you think you can
handle it, try SpamAssassin on a linux box to front end your Exchange
environment.  There are lots of "recipies" available on the internet
that will walk you step by step through setting one up.  The OS and the
software are "free".  But you will need a separate server that can
handle your mail volume, and of course your time investment to set up
and learn to configure.  SpamAssassin does not delete spam.  It only
tags what it thinks is spam.  You can then use a rule at the client
level to place all the spam into the junk mail folder.  SA + the
Exchange Junkmail filter have been very effective in our environment.

I didn't know anything about linux when I started our project here.  We
were also desperate and had no budget.  I had our SpamAssassin box up
and running on a spare desktop PC in about 3 days of "spare" time.  I
think it took about 12-16 hours total.  I used to tweak the rulesets and
mess with the custom rules a lot.  I rarely touch it anymore.  I just
run the upgrades that come out about twice a year.  After our proof of
concept period I did move the installation to a more robust server box
with more ram and raid 1 scsi drives.  We have been using it for almost
2 years now.

Goodluck with whatever you choose!

Subject: [exchangelist] SPAM Blocking for Exchange Server 5.5

Hello everyone,

I'm at my wits end trying to fight SPAM at the client level.  Does
anyone have any good recommendations for SPAM blockers at the server
level?  We are receiving 150-200 SPAM messages per mailbox per day!!!  I
am running an NT 4.0 Server running Exchange Server 5.5.  Our network is
very small - 30 Exchange mailboxes.  

Keep in mind cost, ease of use setting up, configuring, maintaining,

Thanks for any recommendations!
