Very useful.

This review is for a previous version of the add-on (4.0.0).

This sounds like a known problem. You can get a fixed version from https://github.com/lieser/dkim_verifier/issues/279#issuecomment-997386893.

Next time please don't use the reviews to report problems. Use https://github.com/lieser/dkim_verifier/issues or write me an E-Mail (in English or German).
