One can achieve the same effect perhaps but it's not as easy to
understand or explain:
Potential customer question: "How do I communicate that I don't send mail?"
Answer: "You imply in your policy that, in fact, you do send mail, that
all such mail must be signed, but then because there won't be any
signatures you'll achieve your goal."
Customer scratches head: "Why not just a binary flag that says 'I don't
send mail'?"
