Technical Alert: Outgoing emails sent via Sophos UTM being recognized as confirmed SPAM

Sophos issued the following announcement to us:

We are seeing an increasing number of incidents where outgoing emails sent via Sophos UTM with anti-SPAM activated are classified as ‘confirmed SPAM’.

At the moment we have no confirmation that this affects all emails or that it affects incoming emails but we currently cannot exclude this possibility.

Our development team is working with urgency to solve this issue which appears to be caused by the SPAM patterns used. This means that a fix will be provided via live cloud lookup once available, rather than requiring a product or pattern update.

Further information about how you or your customers can report this problem and updates on this issue until it is solved can be found in the following KBA: https://www.sophos.com/en-us/support/knowledgebase/122687.aspx

Thank you for your understanding.
