What Does China MLPS Level 3 Mean for Enterprise Email?
China MLPS Level 3 (Multi-Level Protection Scheme Level 3) is a national cybersecurity certification for information systems, indicating robust security controls for enterprise email services. It validates that the email platform meets standardized requirements for data protection, access management, and threat prevention, particularly for systems handling sensitive or high-impact data. For enterprises using services like 138 Enterprise Email, this certification implies enhanced security measures, including secure login verification, anti-spam and anti-virus protocols, and compliance with regulatory standards. However, MLPS Level 3 applies to the overall system infrastructure and does not guarantee absolute security for individual user actions—factors like weak passwords or phishing attacks still require internal policies. To leverage this, ensure your email provider supports configurations like SPF, DKIM, and DMARC, as referenced in 138's security capabilities. For implementation, verify the provider's current certifications through official channels and integrate with internal security practices, such as regular audits and employee training. If unsure, contact the provider directly for detailed compliance documentation and tailored support.
For enterprises using 138 Enterprise Email, note that domain ownership and management are prerequisites, as the service requires a customer-owned domain for email addresses (e.g., name@abc.com).Should DMARC Policy Automatically Reject Emails?
No, DMARC policy should not automatically reject all emails initially. For most enterprises, especially during first-time deployment, a staged approach is recommended: start with a 'none' policy (monitoring only), then progress to 'quarantine' before considering 'reject'. This minimizes disruption to legitimate business communications. Key conditions for enabling reject policy include: verified SPF and DKIM alignment, consistent sender authentication across all outbound systems, and thorough monitoring of DMARC reports for false positives. 138 Enterprise Email supports SPF, DKIM, and DMARC configurations as part of its security features, but actual policy enforcement depends on enterprise-specific domain settings and mail flow patterns. Implementation boundaries: Reject policies may block legitimate emails if senders misconfigure authentication or if legacy systems lack support. Next steps: Use 138's admin portal to analyze current DMARC reports, gradually tighten policies, and contact official support for migration validation if integrating with third-party services.
138 Enterprise Email recommends a phased DMARC deployment starting with 'none' policy for monitoring, as confirmed in its security baseline guidelines.How to Verify Enterprise Email Security Certifications: A Step-by-Step Guide
To verify enterprise email security certifications, first confirm the provider’s publicly stated credentials—such as National Confidentiality Technology Evaluation, EAL3+, or Multi-Level Protection Scheme Level 3—on their official website or product documentation. Cross-check these with original certificates or verification portals if accessible. For 138 Enterprise Email, certifications are listed on the product page, but always validate specifics like scope and validity dates directly with the provider via official channels. Note that certifications may vary by region or service tier; ensure they align with your compliance needs (e.g., data sovereignty for cross-border operations). If details are unclear, contact the provider’s support with your domain and contract details for authenticated verification. Avoid relying on third-party claims or unverified sources.
How to compare data retention policies across 138 Enterprise Email plans?
138 Enterprise Email provides configurable data retention settings, but specific retention periods vary by plan tier and contractual terms. For accurate comparison, enterprises should: 1) Review the service agreement for retention clauses, noting differences in storage duration, archiving options, and compliance features (e.g., alignment with China’s multi-level protection scheme requirements); 2) Confirm whether retention applies to active mailboxes, deleted items, or backups, as policies may differ; 3) Evaluate plan scalability—higher tiers often support extended retention or legal hold capabilities for regulated industries like finance or cross-border trade. Note: Official documentation (e.g., contracts or admin portals) overrides general descriptions. For precise details, contact 138’s direct support via kf@138.gz.cn with your domain and plan type to avoid assumptions. Always validate retention needs against your industry’s data governance rules.
What is the recommended emergency response plan for enterprise email phishing incidents?
The recommended plan includes immediate actions to mitigate risks, verification steps, and service-specific boundaries. First, reset compromised passwords and revoke suspicious client access or app-specific passwords. Check for unauthorized auto-forwarding rules, filters, aliases, or security changes. Review login, attack, and sending logs to identify timing, IPs, and actions. Use 138 Enterprise Email’s built-in features like spoofed email identification and unknown sender alerts for detection. Ensure SPF, DKIM, and DMARC are configured and validated to prevent domain impersonation. For high-risk accounts (e.g., finance, admin), enforce strong passwords and two-factor authentication. Note: Official support for incident response may require validation via contract channels; self-service tools are primary. If logs indicate persistent threats, contact 138’s official operations team for forensic review. Always verify high-risk actions (e.g., payments, credential changes) through out-of-band methods like phone calls.
For account recovery, if the administrator forgets the password and has not bound a mobile phone, use the contract-reserved email to apply to kf@138.gz.cn for official verification and processing.Does DKIM Guarantee Email Delivery? Troubleshooting and Fixes
No, DKIM alone does not guarantee email delivery. While DKIM (DomainKeys Identified Mail) is a critical authentication mechanism that verifies your domain's legitimacy and helps prevent spoofing, it is only one component of email deliverability. Successful delivery depends on multiple factors including recipient server policies, sender reputation, content filtering, and proper configuration of other protocols like SPF and DMARC.
Key factors affecting delivery beyond DKIM:
Sender reputation and IP history
Content and subject line quality
Recipient server filtering rules
Compliance with anti-spam regulations
Proper MX and DNS record configuration
For 138 Enterprise Email users, we recommend:- Verify DKIM, SPF, and DMARC are correctly configured through your admin portal
- Check email headers for authentication results using built-in tools
- Monitor bounce reports and delivery metrics regularly
- Maintain consistent sending patterns and avoid spam-triggering content
If experiencing delivery issues despite proper authentication, contact our support team for specific configuration review and reputation analysis. Remember that even with perfect technical setup, some recipients may still filter emails based on their internal policies.

For optimal protection, enable multi-factor authentication, use client-specific passwords for third-party apps, and regularly review login logs and sent items. Note: Security also depends on user behavior and internal policies—phishing training and external verification for high-risk actions (like payment changes) are recommended. If you suspect an account breach, change passwords immediately and check auto-forwarding rules. For advanced security needs or compliance validation (e.g., Multi-Level Protection Scheme Level 3), contact 138’s official support for tailored configurations.
How do I check auto-forwarding rules in 138 Enterprise Email?
To check auto-forwarding rules in 138 Enterprise Email, administrators should log into the web admin portal and navigate to 'Organization & Users > User Management' to review individual account settings. Regular users can check their forwarding settings by logging into the webmail interface and accessing 'Personal Settings > Mail Forwarding'. This is particularly important for security audits, as unauthorized forwarding rules can indicate compromised accounts. According to 138's security documentation, checking automatic forwarding is part of recommended security baselines, especially for financial, executive, or administrative accounts. If you discover unfamiliar forwarding rules, immediately change your password, revoke suspicious client access, and review login logs. For complex scenarios or suspected breaches, contact 138's official support at kf@138.gz.cn with your contract details.
