Exactly. You might just forward an e-mail to someone with an action without thinking of the e-mail chain below.

But if you're taking screenshots or photos of a secure e-mail because it doesn't allow you to copy the text, you know you're doing wrong.

I’m not so sure.

I can easily imagine this system “training” users to take screenshots, especially if their correspondents are a little to eager to use this feature. It would only take a few rounds of “I sent you this”/“No you didn’t” with the boss, or the computer “eating” important documents.

Now you’ve normalized this deviance and emails are now spread all over creation (including personal devices) and in a much less searchable format....

Plenty of office workers use screenshots to copy and paste text into emails, etc., just because, so unless you first break them of this habit, using screenshots to copy secure email isn't really much of a signal of awareness of wrongness.
