	Title           : Recommendations for the use of whitelists for email senders transmitting email over IPv6
	Author(s)       : Terry Zink
	Filename        : draft-tzink-ipv6mail-whitelist-02.txt

   This document contains a plan for how providers of email services
   can manage one aspect of the problem of email abuse over IPv6.
   Spammers can send mail from a very large range of IPv6 addresses,
   and this will make current antispam blocklisting technology less
   effective.  This is because email receivers will have to maintain
   excessively large lists of IP blocklists which either consume too
   many resources, or will become stale and therefore ineffective as
   spammers quickly discard one IP address and move onto the next one.

   This document recommends that during the transition of email from
   IPv4 to IPv6, email receivers implement a whitelisting option where
   they only allow email from permitted senders over IPv6 and reject
   or throttle email from everyone else sending email over IPv6.
