One *very* convincing argument not to send an *email* response (reject 
at SMTP is fine) is that it is very likely indeed you'll end up on an 
RBL yourself for doing this. It happened to us when we were still 
bouncing (probably about 8-10 years ago). It was the main reason we stopped.

Reindl,
I respecfully disagree with (a) at least for the UK. It may be the case 
in Germany but I'll be damned if I'm going to give up on my Mailscanner 
- tuned over the years enough that we've never had a legit mail get canned.

Anyway, that's enough for me otherwise this is going to turn into a 
flamewar rather than informational.
