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
