It is enabled by
echo /usr/sbin/rcptfilter > /etc/courier/maildropfilter
That runs rcptfilter in stead of maildrop for the embedded mode
(a.k.a. "whitelisting API"). If called, it will log something unless
everything runs super-smooth.

The $HOME/.mailfilters/* files are done by maildrop, so they won't
play if you use the above maildropfilter setting

You may want to also test stderr, e.g.
printf '#err\n##warning\n###notice\n####info\n' >&2
(handling those '#'s is the only cumbersome code of rcptfilter.c)

Did you try invoking it manually, just to check it runs? E.g.
HOME=/home/testlooser rcptfilter -M rcptfilter -D nnn/mmm
(where nnn/mmm are some numeric uid/gid)
