I've also have heard "bounce" used for an SMTP reject (5xx return),
although that was among people who would never read a standard. I'm not
real worried about that case; and I've never heard the term "bounce
address" used ambiguously. Indeed, the reason I like it is because it
has always had 100% recognition even among people who'd never heard the
term before.
No one is commenting on the alternative I'm suggesting, which is "return
address".
It directly maps to its real function and, of course, the term used for postal
mail.
