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. www.spamassassin.org Goodluck with whatever you choose! -----Original Message----- From: Jason Davis [mailto:JDavis@xxxxxxxxxx] Sent: Monday, February 21, 2005 2:54 PM To: [ExchangeList] Subject: [exchangelist] SPAM Blocking for Exchange Server 5.5 http://www.MSExchange.org/ 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, etc. Thanks for any recommendations! --Jason Davis ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSEXchange.org Discussion List as: Ray.Dzek@xxxxxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Report abuse to listadmin@xxxxxxxxxxxxxx
