[SFOS 18.5MR3] Poor spam detection after update to Sophos Anti-Spam Interface

I am curious.

Are only Home Users seeing this issue? Because it looks like, only Home Appliance are affected by this potential issue. Or does somebody with a Appliance (SG/XG/XGS) have the same issue? 

I am a Home User, setup SFOS in MTA mode.
I do not experience more spam coming through then before the upgrade to 18.5 MR3.

Behind the XG is a mailserver with a second line of spam defence, that doesn't show an increase in activity either.

Same here, but what I noticed is I don't get any confirmed spam in quarantine anymore, and probable spam is not tagged with [SPAM]. Seems those mails are not processed by spam engine and go straight through to my mail server.
What works is the RDNS and RBL checks.

Ok it seems its now working for me. It seems Antispam service was not running properly. Monitoring was not complaining and under "System Services" it was shown as "Running". I tried to stop it, but I got an error.

The solution: Restarted my firewall, and turned off and on the Antispam function in my SMTP policy. Since then spam is properly sent to quarantine or tagged with [SPAM] again.

I confirm this solution. It's a temporary solution, but it works. Stop SPAM rule, stop SASI service, start SASI and start SPAM rule. Working sice yesterday. E-mails are tagged properly. It works also in v19EAP2.

And unfortunately stops working :/

For me its still working, I can see I get all X-SASI headers in the incoming emails. Maybe you need to restart the firewall as I did.
