How to Use DNS Lookup Tools for Email Authentication?
DNS lookup tools can be used to check various DNS records that are crucial for email authentication:
SPF (Sender Policy Framework): Ensure that your SPF record is correctly set up to prevent unauthorized senders from using your domain. DKIM (DomainKeys Identified Mail): Verify that your DKIM record is in place to authenticate your email content. DMARC (Domain-based Message Authentication, Reporting & Conformance): Check your DMARC record to align your SPF and DKIM policies and receive reports on email authentication issues.
