Hi, I am trying to simulate a DKIM failure and have not been able to figure out how.
Goal: test my “report” TXT record actually works. Talking about RFC 6651
I was hoping that with postfix and opendkim running and signing emails I could just turn opendkim off and send an email through and get it to fail, but instead the headers have
I was expecting “fail”
This is a test server so I can beak stuff. Should I just change the public key in the DNS of the key TXT record so it is wrong and send another email through and see what I get ?
Thanks to anyone that knows how to test this stuff. The dkim mailing list seems to be a ghost town.
Was using this link to come up with ideas for a testing plan. https://bobcares.com/blog/dkim-result-fail-bad-signature/
