the postmaster account can be configured (or not) to recieve copies of every NDR (non delivery report) on the domain it serves.
Mis-addressed email should always get an NDR in reply to the originator.
I administer an exchange server and can vouch for the fact that postmaster accounts can be totally flooded.. but, if configured correctly your admins should be able to check it easily, as most of the traffic is caused by NDR reports that are automated and can be filtered out.

Exactly m8 - " any bounce that doesn't do so is incorrectly configured "
You are counting on the mail server being correctly configured and as you and I both well know - this is rarely the case. Have you seen how some of these bounce messages are worded (when they do come through) I have trouble understanding them so I am not sure how a normal EU is going to cope !!!
The point I am trying to make is that there is allways a risk that genuine email will get blocked. Even if the delivery rcpt goes back to the user they are going to have to resend. What hapens if the server is still blacklisted ? It comes back again. By the time the user actualy gets to send the mail it about a week old.
Until there is a way to be 100% sure that a mail is spam then we cant bounce them only flag them. An average user can cope with setting up a rule in outlook to move them to a diferent folder.
I dont know why everyone does not start to use digital sigs. If we all used them then spam could be blocked - block all mails that dont have a sig on them !!!
There simply is not an out of the box solution to spam. We need to track the spammers and boil them in oil. The methods discused here only deal with the problem and not the cause.
We must not forget that this thread is about NTL blocking mail. If people like you and I ran all the mail servers we would not have all the problems we have now. Do you trust NTL to manage blocking correctly - I dont !!!!
