Sign DKIM and spam emails from recipient

Question

Good morning, in our company we use Windows Server 2022 with Outlook 2019.

Some recipients with different domains (e.g. @gmail.com, @live.it, etc.) have reported to us that some of our e-mails are received in their spam (junk e-mail).

We carried out a test for our domain on website MailTester where a good score emerged, however 1 point was lost due to the fact that the message does not contain the DKIM signature.

Our IT manager set the DKIM signature according to the procedure foreseen and confirmed by the reference provider but, inexplicably, with the DKIM signature set, the test score of our domain dropped by 4 points.

After various checks we are told that the DKIM signature setting is correct but we don't know why following its setting the score of our domain drops... and we assume that our e-mails can also reach some recipients in the Spam folder for this reason.

Would it be possible to have your support in this regard?

Are there any settings or particular instructions to follow for setting the DKIM signature?

Thank you

Fabio
