This company has less than 50 users so I'm thinking a high-priced enterprise solution may not be necessary. So far I've come across the following: Firetrust @ http://www.firetrust.com/home/?PHPSESSID=b2f1b4cd2d92a2e147400c0e1da97c5 3 GFI @ http://www.gfi.com/ And a few others listed at http://www.msexchange.org What have most of you all implemented in your environments? Again with less than 50 users I honestly don't think there's a need to break the bank, even though fighting spam is an important issue. I appreciate any responses to this. Thanks Well a year ago I started using CanIt from http://www.canit.ca. It is a *nix based solution using sendmail w/milter support, mimedefang, spamassassin. I have not had a virus get through both Clam Antivirus and file and mime type filtering yet. Plus the ability to use spam assassin and DNSbls + custom rules based on both email body characteristics or header characteristics works very well. Out of the box this software supports greylisting as well this stops much of the spam that is sent via software that doesn't wait for a response. I am currently using a beta copy that has added SA 2.60 support and Bayesian filtration as well. I added support for razor2 and DCC as well. All if the tools used are open source but the combination of outstanding tools and support roaringpenguin.com rock. I am not a Linux expert by any means but I have benefited this past year as have my spam free users. Please feel free to contact me on or off list on this, John Mason
