Yep, I set it to prefer v6 to test and was only noting that, at least GMail,
doesn't appear to apply stricter policies
around delivery any more (likely modulo your IP's existing reputation).

FWIW, when you enable IPv6
I believe this is somewhat out of date. Google did, in my understanding,
originally require DKIM and not assign IP
reputation to v6 addresses, but that appears to no longer by the case. I turned
on v6-outbound on my postfix server and
it has had no problems with Gmail (or any other) reachability.

The change:
/etc/postfix/main.cf:
from: inet_protocols = ipv4 (DEFAULT: enable IPv4 only)
to:inet_protocols = all(DEFAULT: enable IPv4, and IPv6 if
supported)
error is that default main.cf have this line, defaults is already all

According to Google, third of their users access their service via IPv6.
So, Google agrees with the Postfix docs, correct?

I don’t think this is a good idea. You’re right that m
Greetings everyone,
In 2020 we think it would be a reasonable enable IPv6 it by default.
V4 addresses are getting expensive, and new ISP-s and businesses are
moving to V6 with great momentum. Moreover it would help us and others
to reduce complexity in their infrastructure.
