ARC email authentication

[noname]

New Gmail policy for forwarded emails...
Has anyone set up ARC authentication on their Postfix server?

Sigh. Not yet. I hate all the gymnastics to get mail to go reliably to Gmail and Outlook.com addresses (what, you've blacklisted the whole netblock due to poor reputation? Really? My server doesn't send spam and has valid FQDN, PTR records, DMARC, SPF etc.)
