I'm well aware that it's an optional component.
Thank you for that clarification.

You're saying it uses the envelope, not if exists Reply-To, else From? The problem I have with that is that a few of them have returned the email, with full headers, and I see the *only* reference to my email address is in the Reply-To.
You are seeing the "full" email headers. You will not see the envelope headers unless you capture packets or view mail server logs, etc..
