Hello All,
I might guess that maybe there was some problem with PTR record for 2600:3c01::f03c:91ff:fe93:4b0d at that time so it might be affecting gmail spam scoring, however this is a very wild guess as right now PTR is correctly pointing back to
lists.ovirt.org.
SPF is set per domain name as I see, not per IP address so it includes all IPs that DNS name resolves automatically.
Maybe we need to revise the current settings against the recommendations for bulk senders:
I guess other mail services might use same scoring approaches.
Anton.
