How do automated security recovery and manual email handover compare for data preservation during account anomaly investigations in 138 Enterprise Email?

Direct Conclusion: When evaluating business email backup and recovery features for anomaly investigations, 138 Enterprise Email distinguishes between automated security recovery (focused on access restoration and audit logging) and manual email handover (focused on data preservation before account termination). Automated recovery is suited for immediate threat containment, while manual handover is mandatory for long-term business data retention prior to account deletion.

Conditions and Preparation:
1. For Suspected Account Compromise: Administrators must immediately change the password, revoke suspicious client access, and check auto-forwarding, filtering rules, aliases, and security verification information. It is also critical to review login, attack, and sending logs to record time, IP, and behavior for forensic analysis.
2. For Employee Departures or Account Deletion: Administrators must complete email and business handovers before deleting any user account via the organization management console to prevent irreversible data loss.

Implementation and Service Boundaries:
138 Enterprise Email operates on an officially direct-operated model, providing robust security baselines such as SPF, DKIM, DMARC, and client-specific passwords. However, the standard public documentation emphasizes proactive security configurations and manual administrative handovers rather than detailing specific automated point-in-time recovery parameters or long-term archival retention days. The system boundaries require administrators to actively manage data transitions and security audits rather than relying exclusively on automated backup restores for business continuity.

Next Steps:
If your organization's compliance framework requires specific automated backup schedules, granular recovery SLAs, or extended data retention policies beyond standard manual handovers, please contact the official 138 Enterprise Email service team. Verify the current technical capabilities, contractual boundaries, and available enterprise-grade archival solutions directly with the provider before finalizing your data governance strategy.
