Hi,
I looked up lists.ovirt.org, linode01.ovirt.org and ovirt.org on
SenderBase, and all have a good reputation... anyone more familiar with
mail spam handling who can intervene/investigate?
Thanks,
Dave.

As the message says, and I confirm, there is no ipv6 PTR
record. Wearing my ISP hat, we do not favor email lacking
such in our spamassassin rules, and I know that the US ISP
Comcast also down-rates / refuses email from hosts lacking
such

I am not sure who manages ovirt.org's DNS records, but if we can add a

that would be great.

Since Linode is owner of the reverse DNS zone, whoever has access to the
linode control panel.

Ewoud can help you out - we need to add a PTR record for the IPv6
address of linode01.ovirt.org to the DNS so that reverse DNS resolves
correctly.
The issue is that gmail and other email providers check whether the MX
(in this case, linode01.ovirt.org) has a valid IPv6 DNS entry, and
score you down if you don't.
Also, I'd much prefer that we finish the task of moving off the
Linode host. When is that happening?
Are there plans to move the management of the DNS zone off Linode also?
I don't believe we've set a date, or that we have a detailed plan, for
moving services off linode01. The Infra team are migrating services
away on best-effort, available bandwidth basis. The difficulty
provisioning the Rackspace server has not helped.
Cheers,
Dave.

Ewoud can help you out - we need to add a PTR record for the IPv6
address of linode01.ovirt.org to the DNS so that reverse DNS resolves
correctly.
The issue is that gmail and other email providers check whether the MX
(in this case, linode01.ovirt.org) has a valid IPv6 DNS entry, and
score you down if you don't.
Actually this is a valid case we haven't mentioned. There is no forward
DNS either. That means we should also create that.
The alternative is to disable IPv6 for the time being. Since
smtp_address_preference[1] is 2.8+ and we run 2.6.6, we can only use
inet_protocols[2]. Currently we don't listen on the outgoing IPv6 anyway
so I don't think this has any negative impact. If there's no objections,
I'm proposing we change inet_protocols from all to ipv4 this evening.
[1]: http://www.postfix.org/postconf.5.html#smtp_address_preference
[2]: http://www.postfix.org/postconf.5.html#inet_protocols
When we've added the forward and reverse DNS, we can enable it again and
properly support IPv6.

Are there plans to move the management of the DNS zone off Linode also?
Reverse DNS is tied to your IP space and since we don't have PI-space,
Linode owns the IP we use. That means when we move away from linode, the
reverse DNS management of that IP becomes irrelevant.

Hi,
I pushed this up to Red Hat IT services, and it appears they're not in
control of the Linode console. I need to go digging.
