How do you stop rogue emails?

To stop rogue emails, implement robust spam filters and ensure that your email service provider offers advanced security features. Regularly update your email settings to block known malicious addresses and use authentication protocols like SPF, DKIM, and DMARC to verify the legitimacy of incoming messages. Educate users about recognizing phishing attempts and encourage them to report suspicious emails. Finally, keep software and security measures updated to protect against new threats.
