I configured yesterday spf, dkim, dmarc for example.com. Today I got report in xml on my mailbox. Attached. One from addresses has dkim failed - marked in orange. What that means and how to fix it? I use ubuntu 16.04 lts and postfix:
root@s1:~# postconf | grep version disable_mime_output_conversion = no mail_version = 3.1.0 -- *Pozdrawiam / Best Regards* *Piotr Bracha*
