Probably most won't. However, a few may and that would be a few less
calls, which may be worth it.
You are somewhat limited in what you can say, because unless you are
first accepting the mail and then bouncing it back to the sender, you
probably only have the ability to return the single error message from
the SMTP response (and then hope that the SMTP software connecting to
you will bother to pass it back to the sender.)
Currently the József Kadlecsik UCE control patches seem to be my answer
to everything Postfix; but see in particular
<http://www.kfki.hu/~kadlec/sw/postfix_patch.html#restr>
for how to customize the SMTP response text to describe the specific
reason you are rejecting a message.
