Its intended to eliminate forged envelope senders and HELOs (i.e. in bogus
mails). It allows you to score DNSBLs (RBL/RHSBL), HELO, MAIL FROM and client
IP addresses before any queuing is done. It allows you to REJECT messages
which have a score higher than allowed, providing improved blocking of spam
and virus mails. policyd-weight caches the most frequent client/sender
combinations (SPAM as well as HAM) to reduce the number of DNS queries.
