This is software that filters incoming emails to separate out spam through a collaborative technique.
SPAMfighter Mail Gateway creates a unique signature for each arriving message. How the spam filtering is done is by sending these signatures to a central server that determines if the piece of mail is Spam. If it is, the local gateway will be informed accordingly. The local gateway then routes the mail to user`s spam folder rather than the inbox. The SPAMfighter central server also depends on all the gateways working with different users to detect what is spam. SPAMfighter Mail Gateway is powered by more than 7 million SPAMfighters. If enough SPAMfighters report the same spam e-mail, it is instantly removed from all SPAMfighters and users. This makes for immediate spam protection. There is no need for configuration or maintenance. Administrative features allow for complete control over users and the spam detection policies.
