However, if you are willing to recompile your system, perhaps changing references from RFC1035_TYPE_A to RFC1035_TYPE_PTR in tcpd/tcpd.c docheckblocklist() might do the trick. It looks like it would cause -block on couriertcpd (use BLACKLISTS in etc/esmtpd) to do reverse

No. This is the lookup itself, not what's being looked up.
