Right now our servers aren't accessible through IPv6, except through an IPv4 tunnel, and I expect that's true for a lot of sites. Hopefully, domain based reputation services will be better established before IPv6. By which I mean that I hope domain based reputation services (which rely on SPF, DKIM, etc) will be effective quite quickly. I doubt that we'll ever accept email from a domain with AAAA records, but no A or MX record. I hope that others will also adopt this policy when they deploy IPv6 capable installations. -- Ian Eiloart IT Services, University of Sussex 01273-873148 x3148 For new support requests, see http://www.sussex.ac.uk/its/help/ -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
