It seems we\u2019re getting more and more spam. Management wants to stop it from getting to the server, and taking up server space and users\u2019 time.

Management wants to stop it from getting to the server, and taking up server space\u00a0and users\u2019 time. One requirement is that the solution be 100% successful with no false positives. What are my options?- Via the InternetIf you look at the Web sites of vendors that offer spam control (notice I said \u201ccontrol\u201d not \u201celimination\u201d) you should find information and\/or white papers you can give management to help them understand there currently isn\u2019t a way to stop all of the spam all of the time. Consensus is that if you can get 85% to 90% of the spam with minimal false positives along the way, you\u2019re doing really good.\u00a0There are\u00a0potential ways on both the server and client sides to get the spam monster under control.The first involves software installed on the mail server or a server that then relays the "checked" e-mail onto the mail server for final delivery.\u00a0GFI offers a solution\u00a0that uses\u00a0Bayesian analysis\u00a0to "learn" what spam looks like and keep it from getting through. You have the option of blocking e-mail that use foreign character sets if you don\u2019t expect to get e-mail of that type. You can use a combination of white and black lists to further control what mail can and can\u2019t get through in addition to the Bayesian method outlined earlier. Network Associates has a product called\u00a0Webshield\u00a0that checks e-mail for viruses and either strips the attachment or blocks the e-mail altogether.Anti-spam buyer's guideNorton AntiSpam 2004\u00a0allows the burden for setup to shift to the client. This has options similar to what you\u2019ll see on the server side.As with just about anything you could find today, there are open source options as well using languages such as Python that can be deployed on just about any platform regardless of the one on which your mail server is deployed. Look at www.sourceforge.net for the open source candidates. My best suggestion is to look at all the options and see what works best for you.
