Forgive me, I haven't read the whole thread, but you don't run a mail
server on a dynamic IP do you?

On the networks I administer mail will only ever be dropped without a
bounce message if it is a virus or a bounce from a virus (bouncing virii
is a Bad Thing[tm]). Spam will be filtered into a "Spam" folder (which a
lot of users rarely check, so this could be as good as dropped).

OTOH, we outright reject mail for many reasons -- listed on
zen.spamhaus.org (which includes aforementioned dynamic IPs), invalid
recipient address, invalid sender domain, etc etc.
