DMARC: An Advanced Level of Email Protection
DMARC is a protocol that provides advanced control over email authentication. Its primary function is to protect the domain from phishing attempts . Implementing DMARC means establishing specific policies that indicate how non-compliant emails should be handled. These can range from a simple warning to a complete “rejection” of the message.
SPF ( Sender Policy Framework ) is a protocol that allows you to indicate which afghanistan phone number digits email servers are authorized to send email on behalf of your domain. DKIM allows you to add a digital signature to your emails that can be used to verify the authenticity of the messages.
When a mail server receives a message from a sender, the server verifies it using a public key provided by the sender's domain. If the signature is valid, the message is considered authentic.
Working together: DMARC, SPF, and DKIM
DMARC, SPF and DKIM are often implemented together to achieve robust protection, prevent phishing and ensure that only authentic email messages reach the recipients' inboxes.
These protocols work hand in hand: for example, SPF can help identify emails that originate from unauthorized servers. DKIM can help verify the authenticity of messages that originate from authorized servers. DMARC can help take action on emails that fail authentication checks.
