Karsten fixed forward and reverse DNS records for linode01, but I'm not
sure what their policy is on a reverse pointing to a CNAME.

$ host 2600:3c01::f03c:91ff:fe93:4b0d
d.0.b.4.3.9.e.f.f.f.1.9.c.3.0.f. domain name pointer lists.ovirt.org.
$ host lists.ovirt.org
lists.ovirt.org is an alias for linode01.ovirt.org.
linode01.ovirt.org has address
linode01.ovirt.org has IPv6 address 2600:3c01::f03c:91ff:fe93:4b0d

Their policy[1] on IPv6 doesn't mention it specifically:

* The sending IP must have a PTR record (i.e., a reverse DNS of the
  sending IP) and it should match the IP obtained via the forward DNS
  resolution of the hostname specified in the PTR record. Otherwise,
  mail will be marked as spam or possibly rejected.
* The sending domain should pass either SPF check or DKIM check.
  Otherwise, mail might be marked as spam.
