When using the protector to investigate spam mails all engineers directly see the content of each message. Based uppon the AVG law in Europe this could be a risk. Also dirty content as sex(y) images and language we do not want to see is displayed directly. If there is html content it is also shown and therefore noted to the sender.
If we invest we would like to see the message details directly instead of the content.
I only can see Hide Clean and Whitelisted messages for all users in the Mail Archiver
This is not hiding content for other messages and showing details at first.
Please go to Anti Spam > Setup, and at the bottom of the page he will find the option
After Firmware 51.0.1 it is fully possible.
