Spam Blocker Lite enables administrators to block spam at the gateway before it ever reaches the users. Zero client installations and an intuitive GUI make it easy to filter SMTP, POP & IMAP and provide individual quarantines for each user mailbox.

Leverages the best spam filtering techniques including Bayesian Filters, Razor, Realtime Block Lists (RBLs), OCR for image spam and tarpitting.

Both Spam Blocker and Spam Blocker Lite are based on the SpamAssassin project; however, Spam Blocker also integrates Commtouch Anti-Spam to improve detection rates
