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

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?

  • Just FYI, we are affected too. Lots of Spam is passing though since the update from 18.5 MR2 to MR3. We had support apply the NC-90702 fix and rebooted all appliances/services after that, but still spam with a X-SASI-SpamProbability: 89% is passing through and not landing in the quarantine. Case 05204156, maybe you can take a look. We noticed that Spam with a probability of 90%+ is landing in the quarantine, as it was before the MR3 patch. is there a way to modify that variable, so we can set it to 50% or something?
