That is a non-solution.  You are assuming all users have the same
criteria for what is or isn't spammy content.

you stopped premature reading my repsonse - WHY?
look again at the "X-Spam-Status" header below
a single mail sent from gmail to 2 addresses i own

X-Spam-Status: No, score=-10.1, tag-level=5.5, block-level=8.0
X-Spam-Status: No, score=-8.1, tag-level=5.5, block-level=8.0

and in fact both messages got a different score because my coampany address is in "MOST_SPAM" and my private one in "MANY_SPAM"

the same way you reject a mail with a invalid recipient and two valid
ones

Very clever... except you cannot do any content scanning until you've
already accepted all of the RCPT: commands.

and how does that matter?

there is a reason that typical bounce messages contains "to one or more recipients" - and the bounce of the delivering server just contains the response of the destination - nothing new

Care to try solving again?  You solve the problem of different
content-scanning rules for different recipients, with no possibility
of backscatter, no silent discards, and no delays due to tempfailing,
and you'll make a fortune

it is solved, you just don't get it
