Yahoo Domain Keys setup, getting dkim=permerror (no key)

  • 772

I'm working on getting DKIM installed on my outgoing mail server, to help my email deliverability to my Yahoo clients (all legit emails, etc, no spamming).

I've got DKIM-Signature: and DomainKey-Signature: headers being generated, but a test mailer to my Yahoo account had this line in the headers:

Authentication-Results: mta250.mail.re2.yahoo.com from=example.com; domainkeys=permerror (no key); from=example.com; dkim=permerror (no key)

Any ideas what I may have missed?

email smtp dkim domainkeys

    You do not have the proper dns records set up.

    You can test it youself with policy checker and selector checker. Here is a good tutorial for setting the right records. and also and online form for doing the same. It seems that you have SPF records. You should definitely remove them! Here is a case against spf.
