Fixed

 

Unknown characters after Deep CDR

After processing certain emails with Deep CDR, incongruous characters appeared in the text making it unintelligible.

Forbidden emails were quarantined

Forbidden emails (emails that did not match any rule defined in Policy > Security Rules) were unnecessarily showing up in Quarantine.

Files or empty directories left over

After processing, orphaned files or empty directories might have remained in the temporary files space.

Emails marked Failed skipped retry

When Core was failing scans with the result Failed ( scan failure threshold exceeded the limit in the Core side rule, or all engines failed) , emails skipped retries and they were sent straight to the quarantine.
