Errors in Mail signing validity with recieving messages

Hello,

I recently signed up and I got everything working for sending and receiving messages, but I get either “ERROR” or “UNKNOWN” with mail signing. Was there a configuration I missed somewhere?

Thanks!!

To clarify further, this happens on all messages I receive. Hotmail, Gmail

Where are you getting these messages?

Just in my inbox when I click on “View More” in crossbox version of webmail

You may want to report a case of this with the Feedback link in the menu for Crossbox. This isn’t something to be overly concerned about, but may be a case where the logic needs to be reviewed.
