Hi, We use ORFilter, which is free (although you should donate a few $ if it works well for you). http://martijnjongen.com/eng/orfilter/ Works with E2k and E2k3.
It works amazingly well for us. It finds most spam (>90%) with no false positives (depending on how you configure it - which servers to use and of course what type of emails your receive...). It uses DNS-based spam databases. See the following link for a list. http://www.declude.com/junkmail/support/ip4r.htm Of course it isn't a complete anti-spam solution (like the commercial software), but for us (~50 mailboxes) it works well enough. I have configured ORFilter to change the subject of suspected spam email, and then clients can filter it using rules in Outlook (if desired). ORFilter + Outlook 2003's spam-filtering finds pretty much all spam I personally receive (~150 per day). / Erik -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Marty Gavin Sent: den 29 januari 2004 18:49 To: Exchange Discussions Subject: RE: Serverside Spam filter Isn't MS Hotmail using Brightmail? http://www.isp-planet.com/news/2002/hotmail_020919.html BTW, FWIW, we just rolled out GFI MailEssentials two months ago. It's alright. Catches most of the UCE, with some false positives. Worth a look. -----Original Message----- From: Hutchins, Mike [mailto:[EMAIL PROTECTED] Sent: Monday, January 26, 2004 10:36 AM To: Exchange Discussions Subject: RE: Serverside Spam filter I bird told me e2k3 sp1 was gonna have the same spam technology hotmail uses incorporated into it. -----Original Message----- From: Crista Murphy [mailto:[EMAIL PROTECTED] Sent: Monday, January 26, 2004 8:33 AM To: Exchange Discussions Subject: Serverside Spam filter I know I've seen a lot of people going back and forth about good spam scanners for Exchange and I was hoping you guys could help us out. We have a small business hosting about 15 mail accounts on our Exch 2k server. We're most concerned about our own personal accounts because we receive between 300-400 spam messages daily. We'd like to put some filter on the server, but cannot afford GFI or Winternals etc as we are a small company. Does anyone have any low cost, effective, server side spam removal suggestions? I am planning to upgrade to Exch03 and I heard that there was some built in spam filters on that. Would it make a difference just to upgrade?
