They may be using "greylisting" - - which is where an email server sends a temporary error response for any unrecognized sender. Proper mailers will retry after waiting a few minutes, but the theory is that spammers don't bother and just continue on with the next address on their list. That's not really a bounce, and wouldn't record it as such, but he might not know the difference.
