9.706 - anti-spam engine changed to SASI

Alexander Busch

One of the changes is that: Email Protection anti-spam engine changed to Sophos Anti-Spam Interface (SASI)

Anybody has experience with that change? Does it effect the rate of recognition? I haven't figured out yet if the Commtouch Advanced Security Daemon (ctasd) is dropped with this or not. And if so aren't the results from cyren no longer used?

Best regards

Alex

    Hi Alex,

    some observations from our test-installation which holds only "spam-domains":

    • 10 days bevor the update: total 441 mails, from that 419 recognised as spam (111 Quarantine, 195 RBL) ->  old engine recognition rate 95%
    • 10 days after the update: total 326 mails, from that 191 recognised as spam (0 Quarantine, 191 RBL) -> new engine recognition rate 59%

    So from that numbers, the filterrate over all on the new engine is worse. It seems in the new engine only a RBL-filter works, which is not good.

    Hi all,

    here are the spam-filter results from our test-installation for 14 days after activation of the SSSE3 CPU instructions:

    • total 1253 mails, from that 1245 recognised as spam (434 Quarantine, 30 RBL) -> new engine recognition rate 99%

    With that numbers the new antispam-engine seems in the same range or better then the old one.
