Resolve DKIM Failures Postfix
Budget: $10 – $30 USD
My domain’s DKIM TXT record checks out fine on MxToolBox, yet Google Postmaster insists that 100 % of my messages show DKIM-fail. I run my own Postfix server and, a few days ago.
I’m looking for a deep dive into both DNS and the Postfix/OpenDKIM (or equivalent) setup: why the private key isn’t being applied, whether the selector is mismatched, or if something in the recent DNS change is still propagating.
Screenshot of Postmaster Authentication graph showing 0% of DKIM authentication is attached.
Deliverables
• Corrected Postfix/OpenDKIM configuration and any necessary key regeneration
• Evidence (screenshots or headers) of DKIM=pass in Gmail and at least one other major mailbox
• A brief write-up of what was wrong and the steps to keep it stable going forward
Once you’re done, I should see DKIM success climb from 0 % to healthy green in Google Postmaster within the next reporting cycle.
