My point is that if my mail server receives a message with a <> envelope
sender it should not deliver the message intact to the user. It should wrap
that message to make it obvious that is an error report. If it is a spam but
is delivered looking like an error report it loses it's effectiveness as a
spam.

They do exactly that. Problem being that the "generic here is a mail
error" technique also happens to have a desirable feature for spammers -
no bounce back, aka the <> envelope sender.
