Hi Brandon, thank you for your answer.
Our outgoing IPv6-addresses are: 2a01:5c0:63:10[0-8]::1/56 and 2a01:5c0:63:[1-8]::1/56 Our main domains are: inexio.net and myquix.de These domains are under our control, so we are going to enable DKIM for both and SPF for inexio.net. SPF is already enabled for myquix.de. In addition to our private customers, we have about 1.000 business customers, who also send mails from their domains using our outgoing mailserver as a smarthost. We can't force them to setup SPF or DKIM for their domains. I've just enabled maildelivery via IPv6 now for 20% of our mails. As soon as I have an example for actual deliviery problems I'm going to send you these source domains. Are there any general improvements we can do ? best regards, Thomas Von: "Brandon Long" <bl...@google.com> An: "Franck Martin" <fmar...@linkedin.com> CC: "Tony Finch" <d...@dotat.at>, "mailop" <mailop@mailop.org>, "Thomas Wilhelm" <thomas.wilh...@inexio.net> Gesendet: Mittwoch, 13.

Your domain is recovering, but it can take up to 30 days to fully recover.... sometimes longer if people don't mark your mail as not spam. Though, that's only for the domain you're posting from, without details not much more I can go on.

And if you set up a mail receiver with IPv6, do these requirements too, it is an industry best practice (cf M3AAWG.org).

To send mail to Google over v6 you have to have SPF, DKIM, reverse DNS, everything set up to the best anti-spam standards.
