Re: [RETRANSMIT] Re: Radical Surgery proposal: stop doingreverse for IPv6.
Reverse DNS does uses, even for IPv6. They are not necessarily related to authentication. When reverse lookups of the hosts sending me email don't work, this is almost always an indication of spam. It would be nice to use this heuristic as the first line of defence against spam in an IPv6 world. #---------------------------------------------------------------------- # To unsubscribe, send a message to <dnsop-request@cafax.se>.
