I'm happy for them to send bounces but would rather they don't send lots of 
them to obviously forged addresses, and that they know when their bounces 
aren't going anywhere.

This is a reasonable alternative - thanks for this suggestion.

I would however still like to do this and I don't think it's likely to cause

And sends the message where? I simply want to return non-deliverable bounces to
