S/MIME Encrypted message blocked by Data Control Default policy

Question

Hello SOPHOS friends, 
 I'm configuring SOPHOS XMAIL and have the problem that S/MIME encrypted messages are blocked by default Data Control policy.

In the help area of XMAIL are no notices that encrypted mails are blocked: https://docs.sophos.com/central/Customer/help/de-de/ManageYourProducts/EmailSecurity/DataControlPolicy/SophosDefault/index.html#aufgrund-der-erweiterung-blockiert 
 
 Is there a chance to let them pass? 
 
 Best regards 
 Tino

If I'm understanding your question there is a way to accomplish this. You can set header exclusions just set the Message Action to Log and Continue Processing. Actions don't have to be punitive, simply logging is an option. 
 In my example I select Attachment File Type, I select Custom List and then select or include in the extensions list, then set the Action to Log. As long as this policy is above the policy that blocks the file it will allow it. Same could be done using headers.
