Hello, thanks for your response.
As per your suggestion, I set the sign action to PGP Partitioned in the 'Sign Button' policy. I also set the encoding method in my key to Partitioned.
The email is being properly signed within the body of the message, but I am seeing a "PGPexch.htm.pgp" file attached to the emails. What is the file for, and is there any way to stop it from being sent?
Thank you,
