CAMELOT behaves very much like a firewall that sits in front of the mail server. This can prevent the most spammer attacks just before they occur. Unwanted words and phrases are automatically by special text pattern analysis. Bayesian classification methods are used to rate incoming messages and process them according special rules. The help of artificial intelligence in self learning filters can reduce the portion of SPAM to a minimum.

Deerfield.com's VisNetic MailPermit represents a new approach to spam prevention, combining SpamAssasin's rules-based and Bayesian filtering technology with a proprietary challenge-response system to create a barrier between your business and costly, time-consuming spam. Upon receipt of each email, VisNetic MailPermit verifies that the intended recipient is a valid user on the mail server. If the recipient is not a valid user, the email is rejected. The From address on email sent to valid users is subsequently verified against whitelists and blacklists established in VisNetic MailPermit, starting with lists defined at the agent level, then domain and system level. Mail from whitelisted addresses is forwarded directly to the mail server. Mail from blacklisted addresses is deleted. VisNetic MailPermit may be directly integrated with the VisNetic MailServer or may be installed as a gateway to an existing mail server such as MS Exchange, Lotus Notes Domino, Novell Groupwise, Unix/Linux, or Windows-based SMTP servers.
