Attachment 'Unknown' dropped by E-mail and Server Security v10

Dear F-Secure experts

The new E-mail and Server Security v10 is dropping read receipts as an unknown attachment on inbound email.

Exchange 2010 SP3 UR3 is the server on W2K8 R2 SP1

 

How can I allow read receipts to be accepted and where do I turn off the option of unknown attachment.

Kind Regards

Paul
