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

darnoK

Hi everyone,
I am setting up a separate thread as I did not receive any specific reply in other threads.

The case concerns Sophos Anti-Spam Interface after upgrading from v18.5MR2 to v18.5MR3 and from v19EAP1 to v19EAP2.

Before updating, antispam works great in legacy mode, detects a lot of intrusive messages and tags with a prefix (near 99%). After updating, only some messages are detected as spam and tagged (I did not do any changes in configuration).

What it comes from? How can I edit my lists to achieve pre-update spam detection?

Greetings

    Antispam engine also to not work on brand new XGS136 which we buy...

    In log there are a lot of lines like that:

    MSG   May 17 05:03:44Z [1nqpN1-000549-BY]: spam scanning failed, unable to connect local antispam

    Will update fix this issue? Why patch is not released automaticly? Because this is paid subscription and do not work will we receive refund for time of not working?

    Restarting was not possible via GUI System Services - Services. I had to go to the advanced shell and:

    service antispam:restart -ds nosync

    Restart is possible via the GUI.

    Maybe on your v19, but on my v18.5MR3 it was not possible via GUI, I got an error message.

    That was the first thing I tried via advanced shell, via gui its not working. There is no simple solution for this problem like a reboot / restart of a service. Have you tried turning it off and on again is my IT philosophy :P. I'm in contact with sophos support (finally) and provided debug logs. They keep me updated every 48 hours, but yet no solution. Switching back to MR2 was the first thing they suggested which I don't want.

    Appliances has been restarted few times same as anti-spam &smtpd service.

    XG just forward spam and phishing emails to local email server... Most of that spam emails are blocked by mailscanner on email server so simple free scanner detect them...

    All spam emails have header:

    X-Sophos-IBS: fail

    X-SASI-RCODE: none

    X-Sophos-Firewall: smtpd v1.0

    and in log apear:

    MSG   May 18 14:16:53Z [1nrKTs-0004lD-81]: spam scanning failed, unable to connect local antispam

    I have opened case with Sophos support and get response that it is known issue and they escelate issue to higher level to provide patch for issue...
    Will see if they will patch units before next MR1 release...
