This. This is a known issue. A lot of senders who send through Microsoft have
this issue; are you sending through Microsoft? If so we have instructions for
how to fix that by forcing sending through IPv4 when you send to Google.
for Postfix, as a quick test, you can try to set
inet_protocols=ipv4
in your main.cf. If mails to Google then go through, you could revert
the setting and create a dedicated transport for Google recipients.
I don't have a ready to use example, but something like
https://gnilebein.de/4717/mails-mit-postfix-fuer-einzelne-domains-nur-ueber-ipv4-oder-ipv6-verschicken-4/
is what I remember should work.
