Envelope Sender from missing > DKIM failed

Thanks for the report. I'm familiar with SPF and DKIM. Which mailing sending module do you use?

This module doesn't really handle the mail sending part - it's left for the mail sending module that your site is using. Have you checked that normal Drupal messages works (with the same mailing sending module)? If so, I'm happy to investigate if the misconfiguration is in Views Send.

Thanks for the quick response! Much appreciated and very helpful :)

We just sent Drupal password reset mail from this system/domain and that got a 10/10, i.e. DKIM worked in this case. Also in another case, email sent via a custom module on this site passed the DKIM test.

For Views Send we use ‘Mime Mail’ via the ‘mailsystem’, System mailings are sent via Symfony Mailer. There was a reason for this, whether we can simply switch over would have to be checked.

But anyway, you would you say it's almost certainly a mime mail problem?

No, not necessarily, it could also be that Views Sends is trying to set another sender. But Mime Mail is old ...

Switch the system mails to ‘Mime Mail’ via the ‘mailsystem’ and see if you still get 10/10.

Sorry for putting all the testing on you, but currently I don't use the module in production myself. I only test it using DDEV (and mailhog).

OK, we'll test this after our digital event next week, I don't want to change much at the moment, especially as we've solved the DKIM problem on the server side for now.
