After upgrade to dev-python/pyspf-2.0.14-r1, caused by migration from dev-python/pydns to dev-python/dnspython-2.1.0, the Domain_Whitelist_PTR option in /etc/python-policyd-spf/policyd-spf.conf stopped to work. The domain listed in this option is silently ignored. Upgrade to dev-python/pyspf-2.0.14-r2 brought no improvement
