Re: dnssec-analyzer.verisignlabs.com aaaa lookup fail
It isn’t DNSSEC.

OK.. noerr vs. servfail doesn't make all that much difference to me, but I *would* like to understand why looking ip the IPv6 address for that name gives me an error.

I dunno. I've seen some weird stuff with servers on AWS not resolving IPv6 addresses but having a CNAME pointing outside the zone. Which I don't understand, but at least it doesn't return an error so I just chalked it up to them deciding that supporting IPv6 was too much of a pain.

The only thing that blocking one transport like this does is cause email to be unreliable.

But maybe what isn't so fine is me replying only to the list and still getting a 'rejected: Use IPv4' msg. I don't know how the mailing list works; I'm a bit surprised that I can reply only to the list, get the Client host rejected msg and somehow you can still get the msg??

Presumably ISC sent the list message over IPv6 to them and the rejection rules kicked in. ISC sends email over IPv6 and they accept email over IPv6. This is what happens when you put something into the rejection rules which has zero relationship whether something is spam or ham. I just find it interesting that someone using mx01.ipv6help.de as a MX would be so interested in punishing IPv6 use. > Anyway.. best regards > Lee > -- > Visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from > this list > > ISC funds the development of this software with paid support subscriptions. > Contact us at https://www.isc.org/contact/ for more information. > > > bind-users mailing list > bind-users@lists.isc.org > https://lists.isc.org/mailman/listinfo/bind-users -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: ma...@isc.org -- Visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list ISC funds the development of this software with paid support subscriptions.

Well lets look at the sender that started this thread. % dig mx gmail.com +short 40 alt4.gmail-smtp-in.l.google.com. 5 gmail-smtp-in.l.google.com. 30 alt3.gmail-smtp-in.l.google.com. 10 alt1.gmail-smtp-in.l.google.com. 20 alt2.gmail-smtp-in.l.google.com. % dig gmail-smtp-in.l.google.com +short 2404:6800:4003:c01::1b % % dig txt gmail.com +short "globalsign-smime-dv=CDYX+XFHUw2wml6/Gb8+59BsH31KzUr6c1l2BPvqKX8=" "v=spf1 redirect=_spf.google.com" % dig txt _spf.google.com +short "v=spf1 include:_netblocks.google.com include:_netblocks2.google.com include:_netblocks3.google.com ~all" dig txt _netblocks2.google.com +short "v=spf1 ip6:2001:4860:4000::/36 ip6:2404:6800:4000::/36 ip6:2607:f8b0:4000::/36 ip6:2800:3f0:4000::/36 ip6:2a00:1450:4000::/36 ip6:2c0f:fb50:4000::/36 ~all" % Which we verify then sign to say that we have verified the incoming email. But for you email from @gmail.com over IPv6 is “proof” that it is spam and you send back a rejection which says to send it again over IPv4 when none of the senders has any control over the transport being used and no one is going to add special rules to force email to you to go over IPv4 when you advertise MX servers with addresses.
