[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

    Hi Emmanuel,

    the u2d.log is 34mb, there are no entries in EML with the X-SASI-*. I checked valid and spam messages. Both logs files you have requested are dated  at 0850 this morning.

    Hi Emmanuel,

    Do you still want copies of the files even though there is no X-SASI-* in the EMLs? Or do I wait until v19 has been released as GA?

    Helo rfcat,

    Thank you for the follow-up.

    Yes, and if you have any other emails coming since 3 days ago that are SPAM. 

    Regards,

    I have spam mail, but they do not contain any X-SASI entries.

    I will capture the files and forward them to you.

    Hi, any news about investigation? I had reverted to MR2, because spam tags are very useful for me.
