Anti-Spamming and Content Filtering

Hi,

Take a look at the e250 appliance from Network Associates. This device will provide anti spamming, filtering, AV and because it is an appliance (and sits just inside your network) it will work with most other platforms and units.

Fairly cheap option that is easy to manage with EPO

We use Praetor for anti-spam and content filtering with good results. You can define many settings, including approved and banned sender domains, vulgar words, and so on. They will give you a 30 day demo for free. Once the mail is approved by Praetor, we send it to Norton AntiVirus for E-mail Gateways on the same server, when then sends the mail to our Exchange server. Norton is pretty good for anti-spam but it only considers the subject line.

Go to their web site http://www.cmsconnect.com/

We're using SurfControl Mail Filter and Internet Filter. Mail Filter works as mail relay, who accepts e-mails, checks it for viruses, filters it for spam, jargon words, etc. Also it can add "footers" to outgoing e-mails, re-write headers, etc.

Web filter works as sniffer and in case user tries to access "prohibited" page sends "fake" page to user and denies all next requests to that site.

SurfControl provides database updates for both services and has good support.

Good luck.
