Mail exchanger records changed in the last 7 days
MX records control where inbound mail is delivered. A change you did not expect can mean mail is routed somewhere it should not be.
Fix: Confirm the MX change was intentional. If it was not, restore the previous mail exchanger records with your DNS provider.
DKIM signing could not be detected at the expected selector
DKIM adds a signature that proves a message genuinely came from your domain. Missing DKIM weakens deliverability and spoofing protection.
Fix: Publish the DKIM records issued by Fastmail at the selectors shown in your provider admin console.
