Email security monitoring
SPF, DKIM and DMARC in language a business owner can use.
SPF lists services allowed to send mail for the domain. DMARC tells receiving mail servers what to do when a message fails those checks. DKIM lets a receiver verify that a message was signed by a service you authorised.
If DMARC is missing, impersonation of the domain is easier. Publishing DMARC does not stop every phishing email, especially messages that do not pretend to come from your domain.
DKIM is marked unknown when it is not found at common selectors, because a provider may use a selector we did not guess.
