Reverse IPv6

I should add that domains which I own and I'm sending emails do have SPF records setup for my IPv4 and IPv6 addresses.

I have the same setup like you and it works for me for last 9 months. Google doesn't complain and rejects my emails any more, but back in January 2016 they did. For IPv4 revDNS seems to be 24h TTL and for IPv6 revDNS TTL seems to be 1h when I look at IPs assigned to my server by OVH. Maybe you need to wait until cache expire on Google recursive DNS servers. I would wait TTL time and then test again, to see does that help.

I've had this problem sending mail to gmail since I set up my OVH mail server two years ago. I have forward IPv6 DNS set up correctly, and reverse IPv4 and IPv6 set to point to the mail server fqdn (according to the OVH control panel). I can nslookup v4 and v6 in both directions - ip to fqdn and fqdn to ip. Yet still Google sends this stupid message. Any ideas?

Now that would be a long list

In the Manager, go to Web or Dedicated in the upper bar. Then, go to IP in the left bar. There you can manage all your IPs. Note that, on IPv6, you won't see a list of all the addresses in the /64 block; but you can write the IPv6 you want to manage.

Any news here? I don't see an option to manage revDNS for IPv6 /64 subnet assigned to my dedicated server.

I have the same problem here. I don't see option to add revDNS for IPv6 in /64 assigned subnet. However with one IPv4 address assigned to the box has option to edit revDNS.

Can you post a screenshot, please? Censoring personal details and IP addresses, of course.

I'll try to poll technical support.

Here's an image from my Manager: http://i.imgur.com/jxTGBqK.jpg

As you see, the first are some IPv4 blocs. Then goes the IPv6 /64 bloc. When I expand it("+"), I only see the IPv6 addresses I've defined. And the end of the IPv6 block(may be empty at first), you see "You can select an IPv6 from this block by clicking here". Click there, and you will oget a pop-up asking for the IPv6 address and the reverse name for it.

Note that you don't have to "create" all the IPv6 addresses you want to use; you only have to define them when you want to set a reverse name.

When I select the IP tab, I see the server's IPv4 address and can manage its reverse; that is ok. Where can I enter the IPv6 address? The IP tab has not mention of IPv6 anywhere.

Hi, I'm now having this same problem, and can't find the place to add the reverse for the IPv6 from the new management console. I've added the AAAA record and it resolves (forward) correctly. Reverse lookup fails.

When we send emails to Gmail we get this message:


Hi. This is the qmail-send program at ns3365336.ovh.net.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

I have read the supplied link from google, and it might be that there is no reverse configured for IPv6 in OVH managerv3 but when I try to create one I by entering either amusicgroup.eu or ns3365336.ovh.net I get this message:

Cannot resolve NS query. Try again later!

Is this correct or should I be doing something else?
