DNS (Domain Name System) translates human-readable domain names into IP addresses, enabling the internet to locate resources.
DNS plays a vital role in connecting email servers. MX (Mail Exchange) records point to the mail servers responsible for receiving emails for a domain.
Sender Policy Framework (SPF) records in DNS authenticate the sending mail server, preventing email spoofing.
DomainKeys Identified Mail (DKIM) adds a digital signature to emails, ensuring message integrity.
Domain-based Message Authentication, Reporting, and Conformance (DMARC) builds on SPF and DKIM to provide enhanced email security.
MX records specify the mail servers responsible for receiving emails. Understanding and configuring MX records in DNS is crucial for proper email routing.
Implement DNS security measures, such as DNSSEC (DNS Security Extensions), to protect against DNS spoofing and ensure the integrity of DNS responses.
