In this case I would do it before invoking qmail-remote. Similar like
doing DKIM signing, but check the Spam-Status instead. You can rename
qmail-remote and replace it by a script or use this patch:
https://blog.dyndn.es/doku.php/blog/2016/02/01_netqmail-bfrmt. In case
more things should be done the patch is may be more flexible. Just a
suggestion.

This sounds like an idea, I will see if this works out.

I came up with a second in the meantime - as I read "user prefs" for
spamscanner from the database already, I think it should be doable to
have a kind of switch to deny those mails in spam assassing directly,
e.g. by setting the "reject score" dynamically.

You should be replacing the envelope-sender address with one under your
control when you forward messages in this fashion, i.e. after the initial
destination (as specified by the MX record for the domain) has accepted the
message. That means any bounces go to an address you control, eliminating the
backscatter and preventing mail admins around the 'net from being upset with
you.
