DKIM (DomainKeys Identified Mail) is an email security standard designed to help protect businesses and end users from malicious emails. It works by using a digital signature to authenticate emails sent from a domain, ensuring that only legitimate emails from the domain are sent.
DKIM works by verifying incoming emails against a public/private key pair associated with the domain. When an email is sent from a domain, the sender’s mail server attaches a digital signature to the email, which is then verified by the recipient’s mail server. If the signature matches the public key associated with the domain, the email is authenticated and marked as safe.
DKIM can help prevent email spoofing, which is when someone sends emails pretending to be someone else. It also helps to protect against phishing attacks, where malicious emails are sent to users in an attempt to acquire their personal information.
Overall, DKIM is an important part of email security, as it helps to ensure that only legitimate emails from trusted sources are sent. By using DKIM, businesses and end users can be sure that the emails they receive are from trustworthy sources. This helps keep them safe from malicious emails, phishing attacks, and other online threats.
