Mail Tester: Your message is not signed with DKIM

aronmal

I just did a mail test after a long time and was surprised to see only 9/10 points. The last time (I think a year ago) I got 10/10. I didn’t changed that much, just updated and restored my instance, but I didn’t changed the dkim settings and I also have set the records.

Does someone have an Idea what to look for?

Thanks in advance.

Given you said you restored the system, perhaps there is an issue with your DKIM private key? Make sure its there:

Also double check your TXT records and make sure the DKIM entry is correct.

Also check the postfix logs to see if its complaining about anything related to message signing.

Yes, you seem to be right, they are missing. I guess recreating new ones will be just fine. Thanks!
