Email users often have a favorite method of dealing with unwanted content and senders. Some people like the precision of allow/block lists to authorize or block specific senders or domains (often called “whitelisting” and “blacklisting”); others prefer the simplicity of content filtering; still others like the added effectiveness of challenge-response methods.

A similar range of preferences exists for handling the messages classified as spam. Some users want a daily email summary of blocked email; others want to examine their spam quarantine folder directly; still others may choose to divert their daily quarantine summary to an assistant for checking. Some may not want to be bothered with checking spam folders at all, and elect to have any offending mail vaporized.

Our Email Security service has the versatility to accommodate all of these preferences, and more. Importantly, capabilities can be blended to provide more effective protection than can be achieved by using any one technique independently. In particular, customer experience shows that by combining content-independent techniques with content-based filtering techniques, our solution yields dramatic improvements in user control over inbox access.
