Your DKIM signature is not valid

[edica]

Hello,

Finally configured my own DNS.
I tested email to (mail-tester.com) and gave -3 warnings:

Your DKIM signature is not valid

In Mail this checked "DKIM Support"

Thank you.

* check permission/ownership on files: dkim.pem / dkim.pub
* check s-parameter - dkim_selector and your dns-record for this selector.

and for last resort ;-)
* try to disable/enable dkim
