What do most people do?
Companies who wish to reduce the number of spammails have uptil now had the following possibilities: • Create a simple filter in the e-mail program and throw e-
mails in the ”Junk mailbox”
• Order and use a simple spamfilter and sort out 20-50% spam and risk real e-mails being blocked aswell.
• Do nothing and delete the spammail when it has arrived.

Misunderstandings!
• ”A firewall stops spam!”
• ”I’ve deleted those messages in no time!”
• ”It (spam) will probably go away by itself!”
• ”We haven’t had a problem so far, so I don’t suspect anything will come our way!”
• ”Just sign off the mailing list and You won’t recieve it anymore!”

Why not use Outlook to filter?
• The function ”add to junk senders list” simply adds an e-mail address that probably doesn’t exit. A minute after You’ve added the e-mail address, a similar spammail could be received from another e-mail address.
• The spamsenders are clever enough to get passed almost any filter in Outlook.
That’s why we have to use more drastic measures to get rid of spam.

The 5 spamfilters
820 intelligent spam/antispam rules
These rules are made specific for detecting wether or not an e-mail is spam. The rules add or subtract points to the specific e-mail, ex. if the e-mail includes known spam language, then points are added.
DCC (Distributed Checksum Clearinghouse)
DCC checks the content of en e-mail and gives it a unique score. Should this unique score appear in over, say 1.000.000 e-mails, then there is a good possibility that the e-mail is spam. DCC servers is constantly updated everywhere on the Net and we check every e-mail against these.servers
STA (Statistical Token Analysis)
STA uses the Bayesian method to learn the local ”language” of the e-mails going through the STA filter. The filter learns which e-mails are ’good’ and which are spam and in that way are able to give better points to classify the e-mails.
RBL (Realtime Blackhole Lists)
RBL is the e-mail blackbook. If Your mailserver is open for rely You can be quite sure it will be listed here quickly. We check whether or not an e-mail comes from a mailserver listed in one of the many RBL servers we check. Different RBL servers has different priorities.
Personal Black & White lists
Finally the customer is able to produce their own blackbook. In the reportcenter You can easily add an e-mail address You want to block or recieve from. This also helps the customers to get rid of those ”hard-to-sign-off mailing lists”.
