It looks like the only record type I can "replace" with via RPZ is a CNAME; is this correct? That may be a somewhat limiting factor at some point in the future (e.g. MX records pointing to CNAMEs is expressly forbidden by RFC2181, which does tend to break a fair bit of assumptions MTAs make)... -- Jackrabbit
