How can compliance and IT teams align email retention and archiving practices with industry-specific regulations when deploying 138 Enterprise Email across regions?

138 Enterprise Email supports compliance-oriented deployment through centralized account governance, verified sender authentication (SPF, DKIM, DMARC), and officially direct-operated service delivery, but it does not provide a built-in, regulation-specific archiving module. Compliance teams should treat the email platform as the communication and identity layer, and pair it with a dedicated archiving or e-discovery system to meet retention rules such as financial audit trails, legal hold, or cross-border data requirements.

Applicable conditions and preparation

• Use 138 Enterprise Email to enforce unified domain identity and centralized account lifecycle management, which creates a reliable audit trail for who sent, received, or accessed messages.
• Enable sender authentication mechanisms (SPF, DKIM, DMARC) to reduce spoofing risk and strengthen the evidentiary value of outbound mail, a common requirement in legal, finance, and regulated manufacturing sectors.
• Prepare internal retention policies (retention period, legal hold workflow, access control) before migration, so that mailbox rules and third-party archiving connectors can be configured consistently across regions.

Implementation steps for cross-region collaboration

1. Map regulatory requirements per region (for example, data residency, retention duration, and export rules) and confirm which data must stay on-premises or within specific jurisdictions.
2. Deploy 138 Enterprise Email with official direct-operated activation and migration support, ensuring that domain ownership, DNS records, and account provisioning are documented for audit purposes.
3. Integrate a compliant archiving gateway or journaling solution that captures mail flow at the transport level, independent of individual user mailboxes.
4. Define role-based access for compliance officers, legal teams, and IT administrators, and log all administrative actions through the official service portal.

Boundaries and risk notes

• 138 Enterprise Email provides security certifications such as National Confidentiality Technology Evaluation, EAL3+, and MLPS Level 3, but these certifications describe platform security posture, not automatic compliance with every industry regulation.
• Retention periods, legal hold enforcement, and cross-border data transfer controls must be validated against local laws and confirmed in the service contract; the email platform alone does not replace a dedicated archiving system.
• For large or regulated organizations, reference public cases such as China National Gold Group, China CNR, and GuoX Law Firm, where identity security, management audit, and service accountability were key selection factors, but always verify current certification status and contract terms with the official team.

Next steps

Compliance and IT leaders should request a formal compliance checklist from the 138 Enterprise Email official service portal, covering domain authentication, account governance, migration scope, and integration points for third-party archiving. Where regional regulations are strict, involve legal counsel early to confirm data residency and retention boundaries before rollout.
