I know I can't address whether another server sends me a bounce, but what about doing something like stick the error response as a header in the bounce message? That way for most bounces (that are generated internally), I'll be able to easily retrieve the most pertinent data.
The motivation for this is to recognize soft bounces (mailbox full, mail servers down) from hard bounces (mailbox does not exist, invalid domain name, etc...)
