Fwd: IPv6 Statistics was Re: please fix your broken DNS server
List,

Some help here please. I am at a loss as to why I can't send mail
to the City of Milwaukee. I get.

The MX records are:

Hence dual stacked sendmail refuses to send mail to milwaukee.gov

I have ResolverOptions=WorkAroundBrokenAAAA in my cf file.

The reply from my public servant is:

Well, it's marginally more than academic at this stage. He has three
years to become ipv6 aware, according to:

http://www.whitehouse.gov/omb/legislative/testimony/evans/evans052905.html

From the look of it, state governments may have to "interface" with ipv6
systems, which presumably is incompatible with rejecting AAAA lookups.

Better still, send his reply to his boss along with the URL above and
ask him/her if this is the standard Milwaukee state government manner
for dealing with technical requests.

Cool reply, though. Why don't you print it out and use it as an office
dart-board? :-)
