I would look into getting a new ISP. Not much you can do about other people's systems if they are using dnsbl's.

The software can be configured to only modify the subject (allows for client side filtering of the spam) or to move the spam to special mailbox or just delete them straight away. / Erik -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Matt Plahtinsky Sent: den 28 oktober 2003 17:22 To: Exchange Discussions Subject: SPAM filtering on a budget Hello list, I know SPAM filtering products have been covered in great detail but I'm having problems finding a good gateway SPAM filtering product that's not going to cost me a lot of money. I have a small organization of about 100 users. The products that I have found that are reasonably priced are Xwall ($360.00) and SpamAssassin (free). My problem with SpamAssassin is that I don't know the first thing about Linux so that's out of the question. Xwall seems like a good product but I want a few more to compare. My budget won't allow for more than about $800.00. What cheep products are you using. Good/Bad experiences. Any help with my product search would be great.
