IPv6 DNS Blacklist support?

Hi there

I see that also in 3.1.0 there is still this entry preventing any further 
checks of IPv6 addresses in Received.pm:

  $ip = Mail::SpamAssassin::Util::extract_ipv4_addr_from_string ($ip);
  if (!$ip) {
    dbg("received-header: could not parse IPv4 address, assuming IPv6");
    return;   # ignore IPv6 handovers
  }

It is planed to get support for IPv6 based DNS Blacklists soon? This leaking 
support is preventing us turning on IPv6 on our Mailservers as our Mailadmin 
fears Spamers would notice and then try to spam via IPv6 avoiding being 
blocked.

There are 'experimental' IPv6 Blacklists (my own one :-).

host -a 
2.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.blacklist.woody.ch
