We do subscribe to Spamhaus' DNS-based blocklist.  They are
invaluable, and integrate nicely with DCC.  Most of our rejections
are based on their ZEN database now.  However, nothing compares
with cryptographic signatures like DKIM.  These prevent forgeries.
That's why we would like to make increased use of DKIM.
