CAMELOT Messaging Security - Full featured server side messaging firewall that is designed to fight SPAM

CAMELOT is a server side based spam filtering solution that behaves very much like a firewall that sits in front of the SMTP Mail Server. Messages are received through the CAMELOT Gateway and are forwarded to a standard mail server after they are successfully processed. The SMTP handler verifies all the parameters of the SMTP transaction and denies all further processing as soon as an invalid incident occurs. This prevents unauthorized access before the message is delivered to the mail server. All messages are then subjected to an extensive content examination. The CAMELOT Content Processor allows for several methods of Analysis and supports configurable properties and the order of Execution can also be individually adjustable. Different Policy profiles for each network segment and/or domain are used to perform detailed content processing for all types of requirements. The content examination process works with the Combination of multiple analysis technologies. Unwanted words and phrases, as well as dangerous HTML references, can be detected 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 filter systems can reduce the portion of unwanted messages to a minimum. Also pornographic contents in images can be detected in this way. Messages can be scanned by third party anti virus products through special interfaces. Infected attachments can be removed from the infected message and forwarded to special quarantine zone.
