Email encryption check before accepting for transmission

We need to ensure that emails sent by some of our users are encrypted (medical records, reports, etc) before they are sent. We only accept out going mail from our local users by submission (port 587). I realize that this is really the job of the MUA, but I would like to check that emails are

Dr. Wietse, Thank you for your valuable time, not just for this question, but for the entire postfix product. If I understood you correctly, increasing the hop count limit may help in this case. I only see 1 or 2 headers that are being added, but I am not sure. I can try changing the limit and
