Just consider the many transactions with addresses such as:

   no-reply @ validdomin.com

that many feedbacks system use today, including bad guys and the bad/good direct marketing people.

What is the envelope address for these messages?

The ones that end mail to me (about fifty addresses in my personal mail archive, mostly noreply@, some no-reply@, some others) generally use the same address,and it's valid in the sense that the address is syntactically valid and that mail to the address is accepted by the best MX for the domain.

I would not bet that mail to such an address is stored on disk, or causes any reaction other than (at most) an autoresponse. But YMMV.

If you mean that the From and Return-Path are both use the noreply type user id, then they are unable to see bounces. I just checked my archives for noreply and no-reply mail and all the messages have a non-noreply type return-path. The envelope address that I was referring to is what becomes the return-path.
