domain-based message authentication reporting and conformance or d mark is an open protocol to prevent phishing attacks via impersonation d mark compiles the signals from SPF and deacon to existing technologies SPF allows the domain owner to specify which IP addresses are authorized to send an email on their behalf D Kim uses an encrypted signature to verify if an email sender is who they say they are and gives the key to the recipient to check back with the sender's DNS records they both produce individual authentication identifiers that help validate email in different ways if you have implemented SPF and deacon the receiving server can identify who an email is from but does not know if all your traffic is properly configured so cannot act on this knowledge d mark combines the results of SPF and deacon to accurately identify if an email is from either an authorized sender or a fraudulent impersonator and can therefore actively block phishing attacks by enforcing a policy with d mark you can instruct receiving servers on how to deal with emails that use your domain by setting your d mark policy to accept all email policy none send email that fails validation to spam policy quarantine actively reject all unauthorized email policy reject initially when you start - you see mark it delivers compliance reports but does not send emails to spam or reject it these reports can then be analyzed by on d mark to help fix your SPF and deacon configuration after which you can switch your d mark policy to actively reject malicious email the compliance reports only contain information about the sending and receiving email service an SPF D Kim and D mark validation status so no sensitive email data is ever shared find out if your domain is secure at Andy mark calm and start blocking fraudulent email today on d mark actively blocked phishing attacks increased email deliverability you [Music]
