Re: ipv6 only DNS?
I would suggest to read RFC3901/BCP91: ³DNS IPv6 Transport Operational Guidelines² on this topic. - Alain.

Re: Is your ISP blocking outgoing port 25?
It's a pity that MAAWG or another group hasn't written a specification for the automatic downloading of configuration (with certificates, to be sure, for some kind of repudiation) and the update thereof, for adoption by the leading consumer e-mail clients. MAAWG decided it's not in the standards business, but it does BCPs pointing at standards elsewhere (mostly the IETF) that it encourages people to follow. Write a standard that people can use, and I don't think I'd have much trouble getting them to endorse it. It's an interesting design topic, particularly the bootstrap question of how the client decides where to look for its configuration. A lot of this stuff is already available via DHCP, but of course a key goal here is to set config info the last across reboots on different networks. Followup to IETF-something, I suspect. R's, John
RE: Is your ISP blocking outgoing port 25?
It already is used by Microsoft. Do a google for +Microsoft +Autodiscover. It is used by Outlook for Windows, Entourage for Mac, the iPhone and Windows Mobile devices. Like you suggested, it uses DNS based on the users email address and looks for a series of resolvable addresses the easiest being autodiscover.domain-name.tld (it has others because of SSL cert flexibility). It uses that address to download an XML file. The only tricky thing to set it up is that a lot of the documentation out there is dated. It has changed since it was first released and a lot of the documentation on technical blogs, and even on Microsoft's web site are incorrect. Once it's setup, however, it's great.

Based on what the e-mail client could support, the desired settings would be displayed, and upon end-user approval, applied. End-user approval? That means support calls, ISPs wouldn't like that. I can believe something like this could be made to work, but I would think hard about all the way that web sessions can get screwed up or hijacked before I persuaded myself that a scheme was likely to work where it needed to work (e.g., when connecting to a hotspot that hijacks all web sessions until you log in) while not being subject to hostile spoofing. Followups definitely to IETF-something. I would suggest following up at disc...@apps.ietf.org; the folks there can point you to things like RFC 2244 (ACAP, the Application Configuration Access Protocol), describe why that got turned in XCAP by the RAI area (RFC 4825, primarily used in SIP contexts but designed to be multi-use), and caution you that the many hours spent designing these things have not generally born fruit in the marketplace. Is this possible for email? Sure. With strong support from a vendor with a tied house model (e.g. RIM or Apple), it might even get to be popular. But as a general purpose approach, it has not hit that sweet spot. regards, Ted Hardie R's, John
Interview: Patrik Fältström on the role of go vernment in IPv6 deployment
We uploaded another interview: http://www.youtube.com/watch?v=zrE1TEan4Jo To make sure we cover as many areas of the industry as possible, we asked Patrik Fältström on the role of government in IPv6 deployment. Patrik is Senior Consulting Engineer with Cisco, but has served as an advisor to the Swedish government on IT policy since 2003. In the interview, he makes a note about the American government as well. I hope you enjoy it. If you have feedback on specific topics you would like to see covered in future interviews, please let us know. We appreciate your comments. Alex Band RIPE NCC
