[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

    Hello,

    Would it be possible to get the output of the /log/u2d.log and /log/sasi.log as well as a few samples .eml files via DM (especially interested in the X-SASI-* headers) so I can provide this info to the pertinent team to investigate.

    Regards,
