Hi Marcin,

you can modify qmail-scanner to exit with error code if spam score is over a given value
(usually higher than default score, e.g. 10 rather than 5)
Unpatched qmail would return - during the smtp session, not as a bounce - an
"administratively prohibited" message to the sender.
It is straightforward to add a new exit value  to qmail and have that tell the sender that their
message was considered spam.
You can do this right away, but you are still encouraged to install whatever matches your system
setup and rejects mail to non-existant users
