[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

    None of my email messages come with any X-Sophos information, the messages that I can see in my email account.

    Hello Karlos, 

    the thread is a bit cluttered. So its confirmed that spam engine has problems on a XG210 with 18.5.3? 

    I had the problems in the sasi log: 

    vector::_M_range_check
    Rebootet and its a bit better but the error still persists.
    Major problem on smtpd.log is:

    spam scanning failed, unable to connect local antispam

     

    But sometimes it does work. Found mails this night with:

    spam scanning result: 'NonSpam'

    and

    spam scanning result: 'Confirmed'

    We use IPv4 for all clients etc, but for compatibility our Sophos has an IPv6 too. For instance, Gmail Mails are delivered via IPv6 to the MTA. 

    More information in my ticket: 05194806 

    Is it possible to get the fix as hotfix? MR-4 will take some time I guess, and we getting all sort of porn spam etc. now.. this is a little sad for an expensive mail solution

    PS: your telephone indian support is bad, he tried to mess up with my exceptions and allow malware and drop all spam (even probable spam) 

    I actually think he doesn't know what exception means because he said something like, okay RBL is on.. 
    no its skipping RBL (but in our case only for / from internal systems, like ticket systems, phone systems etc) 


    Thanks that this community is here, otherwise we would drop Sophos.

    When can we expect SFOS 18.5 MR4 or a hotfix? I don't get any anwser on my ticket since a week. Your paid support is a joke.

    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.
