To check your email authentication, start by ensuring SPF, DKIM, and DMARC are properly configured in your email settings. SPF (Sender Policy Framework) helps to detect spoofing, DKIM (DomainKeys Identified Mail) verifies the sender’s identity, and DMARC (Domain-based Message Authentication, Reporting & Conformance) provides detailed reports. You can use tools like MXToolbox or MailTester to check and validate these settings.
