Spam Blocker Lite enables administrators to block spam at the gateway before it ever reaches users. Zero client installations and an intuitive GUI make it easy to filter SMTP 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 MailShell Anti-Spam to improve detection rates.

Quarantines for each mailbox enable users to manage their own spam folders without having to track down an administrator.
Personal Passlists enable users to designate specific email addresses as “trusted” without having to bother IT staff.
Image-based filtering scans images within emails to stop this new, pervasive spamming technique.
Reports give a comprehensive view of the spam on your network, including the source of the spam, ham-to-spam ratios, trending and stats per user.

Spam Blocker Lite scans email and identifies spam. The status tab provides an overview of all messages received, passed, dropped, quarantined, etc.
Spam Blocker Lite scans any email transported via SMTP. The Email tab has additional settings for you to choose from. For example, by selecting “Scan SMTP”, you can select the level of Strength (the higher the value, the more sensitive Spam Blocker is to spam), and the appropriate action. Advanced configuration SMTP options are available as well.
