An Aggregate Report, also known as a DMARC Summary Report, provides an overview of email authentication results across an entire domain. It includes data on the volume of emails that passed or failed DMARC, SPF, and DKIM checks.
Authentication in the context of email refers to the process of verifying the identity of the email sender. DMARC, DKIM, and SPF are protocols used to authenticate emails and protect against email spoofing and phishing attacks.
A Cryptographic Signature is a digital code generated using a cryptographic algorithm. It is used in DKIM to verify the authenticity of the email sender and ensure that the email has not been altered in transit.
DKIM (DomainKeys Identified Mail) is an email authentication method that uses cryptographic signatures to verify that an email was sent by an authorized mail server and hasn't been altered in transit.
DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol that helps protect your domain from email spoofing. It allows domain owners to specify how unauthenticated emails should be handled.
DNS (Domain Name System) is a system that translates human-readable domain names (like www.example.com) into IP addresses that computers use to identify each other on the network.
DNS Records are entries in a DNS database that provide information about a domain, such as its IP address, mail server, and authentication policies. Common types include A, MX, CNAME, TXT, and NS records.
A Domain Name is a human-readable address used to access a website, such as www.example.com. It is registered through a registrar and points to the IP address of the web hosting server.
A Domain Owner is the individual or organization that has registered a domain name and has control over its DNS settings, including email authentication policies.
An Email Receiver is the email system or service that receives emails on behalf of the recipient. It is responsible for processing, delivering, and applying email authentication checks on incoming messages.
Email spoofing is a fraudulent practice where malicious actors send emails that appear to be from a legitimate domain, usually to deceive recipients into divulging sensitive information.
Header Fields are components of an email header that provide information about the email's sender, recipient, subject, and other details. In DKIM, specific header fields are included in the signature.
An IP Address is a unique string of numbers separated by periods (IPv4) or colons (IPv6) that identifies each computer using the Internet Protocol to communicate over a network.
A Mail Server is a computer system that sends and receives email. It uses email protocols such as SMTP, POP3, and IMAP to handle email delivery and retrieval.
An MX (Mail Exchange) Record is a type of DNS record that specifies the mail servers responsible for receiving email on behalf of a domain.
Phishing is a type of cyber attack where attackers send fraudulent emails pretending to be from reputable sources to trick recipients into revealing personal information.
A Selector is used in DKIM to specify which DKIM public key should be used to verify the signature. It is included in the DKIM-Signature header as 's=selector'.
SPF (Sender Policy Framework) is an email authentication protocol that specifies which mail servers are allowed to send email on behalf of your domain.
A TXT Record is a type of DNS record that allows the domain owner to store text information in the DNS. It is often used to include SPF, DKIM, and DMARC policies.
