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?
We have the issue that there are no mails in quarantine since we installed the update. Looks like we don't get any spam mails. Opened a support case now. Let's see how Sophos can help here.
Good call, Alex! Indeed, zgrep shows that the last appearance of ctasd in the SMTP logs was just before the Up2Date to 9.706 in our instance in AWS.
The last line with ctasd:
