Mail warning from Google

As of today I am getting mail warnings from Google. Like the one below. It says that the mail cannot be verified as coming from the community.

Any idea how they verify, i.e. what they are missing all of a sudden?

Usually an SPF record and Domain Keys DKIM will help prevent this. Most of my emails from go to spam because of the the missing SPF record.

Here is how google is looking at the email. I think an SPF record authorizing should help.

ARC-Authentication-Results: i=1;;

Thanks, I am looking into it. Our nameserver has an SPF record for, I’ll have to figure out, why it isn’t recognized…

This is also a good site to check the setup.

It shows the MX record, but no SPF record.

Thanks! SPF record should be ok now, I didn’t yet figure out whether our provider supports DKIM on his mail servers as well. But I hope that the Google warning is already mitigated by the SPF record, can you confirm?

The problem rains the same. Maybe the DKIM and DMARC records are required as well.

Problem with authenticated e-mail not working is back (again).
