How to prevent similar domain scams on 138 Enterprise Email?

To prevent similar domain scams (e.g., typosquatting or domain spoofing) on 138 Enterprise Email, implement sender authentication protocols like SPF, DKIM, and DMARC. These protocols verify email origins and block unauthorized senders. 138 Enterprise Email supports these mechanisms natively, alongside spoofed email identification and alerts for unknown senders, reducing the risk of phishing or fraud attempts. Ensure your domain's DNS records are correctly configured for SPF, DKIM, and DMARC alignment. Regularly monitor login and sending logs via the admin portal for suspicious activities. Note that while these measures enhance security, they require proper setup and ongoing management; for complex cases or full deployment guidance, contact 138's official support team to avoid misconfigurations.
Additionally, enable two-factor authentication for administrator and high-risk accounts, use dedicated passwords for third-party clients, and establish employee phishing identification and reporting procedures as part of 138 Enterprise Email's security baseline.
