Hi folks,
I got a problem, and was wondering if you could get me some help.
I'm currently trying to do the RDNS mail server test, which is failing with
Failed to get AAAA from MX or your DOMAIN
Looking at some info from here, this is what it tries to do:
Professional: Verify that your MTA has working reverse DNS (ex: dig mx $domain +short ; dig aaaa $mx +short ; dig -x $mxAAAA +short)
Now, I get the 2 first thing right:
debian:~# dig mx derchris.eu +short
10 mail.derchris.eu.
debian:~# dig aaaa mail.derchris.eu. +short
2001:4dd0:fd19:fefe::2
But the PTR check fails:
debian:~# dig -x 2001:4dd0:fd19:fefe::2
; <<>> DiG 9.7.3 <<>> -x 2001:4dd0:fd19:fefe::2
;; global options: +cmd

Now, I use INWX.net for all my domains, and also use their NS.
I believe I have setup the correct PTR records there.
As my hoster has no native IPv6, I did setup an old Sixx tunnel + subnet.
My mail server is running as a Xen VM, and has an IPv6 from my Sixxs subnet.
Ping/Login all is working.
Sixxs asks to add Reverse Delegations on their website, where I added my NS.
However, it seems like I always end up with only the AUTHORITY SECTION from the dig output when I try to query my PTR records.
I do believe that I need to run either my own NS, or some other service where I can edit/add Zone files.
I'm out of ideas at the moment.
Looking at the next levels, I should be able to pass them.
It is just the RDNS at the moment.
Any help much appreciated.
Thanks,
Christian
