I'm pretty new to email authentication, and I've run into a problem with my DKIM alignment while my SPF seems to be working fine. I'm using OSX-appsuite as my email manager, but it looks like my DKIM signature is coming from vadesecure. I really need some guidance on what to do to get my DKIM to match. When I check using learndmarc.com, it shows that I've included a DKIM signature, and the public key was retrieved successfully. The validation passed, but it's indicating that the DKIM domain doesn't align with my sending domain (oxsus-vadesecure.net vs mysite.com). Can someone help me understand how to resolve this DKIM mismatch?

You need a separate DKIM signature for each unique domain you're using. Although you can technically use a DKIM signature from another domain if you have the private key, that's why you're getting a relaxed alignment status. Also, it's a good idea to set up DMARC records for your email domains to help improve delivery and compliance.
If you're unsure about how to adjust your DKIM, reach out to your email service provider. They should modify their DKIM signatures to align with your mysite.com domain instead of oxsus-vadesecure.net.
Totally agree! DMARC compliance is essential, especially with tightening standards.
