Re: ipv6 PTR record; was: Re: Fwd: Bounce action notification
Thanks for the hints Russ!
I am not sure who manages ovirt.org's DNS records, but if we can add a
PTR record for 2600:3c01::f03c:91ff:fe93:4b0d and that solved the issue,
that would be great.
Who can do this?
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
[herrold@centos-6 ~]$ host 2600:3c01::f03c:91ff:fe93:4b0d
Host
d.0.b.4.3.9.e.f.f.f.1.9.c.3.0.f.0.0.0.0.0.0.0.0.1.0.c.3.0.0.6.2.ip6.arpa
not found: 3(NXDOMAIN)
[herrold@centos-6 ~]$
I would start by getting it set
