This is what we don't want to do. Immagine it is a false positive.
The Maillogs of the sender, any maybe even an MDN Messages confirm, the email
has been received by the server. So that email just disappears. This is what
we want to avoid.

Yes, but I know what spam action (reject or accept) the individual recipient
has. So I can first handel alle the recipients who want to reject spam and
tempfail all the others, and the vice versa. I do not need to know if the
email will be handled as spam at that point. I just make sure, that if it will
be handled as spam, I only have recipients that want spam rejected.

After some more Googleing I think I found a solution.
For each smtp session, MIMEDefang uses a different spool directory and CWD's
to that directory.
So I am now writing the recipient and spam settings to a file in the actual
CWD and on each recipient I can get the count and what kind of recipients I
accept from that file.
