Domain source compliance needs improvement

So I’m now getting reports for my domains but under tasks it says “Domain source compliance needs improvement” but everything is green and there’s an Ignore checkbox. Can I indeed ignore this?

As is often the case, It depends.

“Domain source compliance needs improvement” usually indicates that some mails are regarded as non-compliant. If someone is spoofing mails from your domain as sender, then those mails should be non-compliant, and can safely be ignored. The improvement recommendation may be based on a longer range of data than the 7 days used for creating the Domain Overview.

However, if some part of your company is sending mail that has not been authorised using SPF and/or DKIM then those mails will likely also be non-compliant, and should be identified, documented and authorized.
