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

Maybe I'm not that disappointed, because I always used some extra RBLs. These are zen.spamhaus.org, ix.dnsbl.manitu.net, b.barracudacentral.org and bl.spamcop.net.Give it a try. Btw. something I learned not log ago, these extra RBLs are always rejecting emails. The settings in the GUI only have an effect of the Sophos own tests.
RBLs are nice but will generally not help when the spam comes from abused/hacked accounts or from spam gangs which quickly change their infrastructur/IPs (which most of them do). Additionally on most of the RBLs you quickly run in a volume limitation when you use DNS-resolvers form providers (which is mostly the case).
Dear Sophos you must had content matching (words/sentences, URLs, GIFs...) in your spam engine, why is this obviously not working in the new version?
Josef, i know it's only 5 Days, but is there anything you can tell already ? i guess after 5 Days there must at least one or 2 mails in quarantine
short answer, yes now are many mails in the quarantine and the anti-spam engine seem to work.
hmm, then i ask myself whats wrong with my installation ?
i made a new install and imported a backup. so where is the issue here ?
do u use profile mode with the smtpd proxy ?
also IPS is on 0
antispyware is 0
webfilter is 0
what the heck is going on here ?
maybe someone from the dev's could look at this, because i have no clue what i can do here and where to look.
