Introducing Email Archiving — Long-Term Retention for OpenEFA®

Enterprise-Grade Archiving Now Available as an Add-On

We're excited to announce Email Archiving, a new enterprise add-on for OpenEFA® that provides long-term email retention with full searchability, compressed storage, and raw message recovery.

The Problem

For many organizations, keeping email around for 90 days isn't enough. Legal holds, regulatory requirements, insurance audits, and internal compliance policies often demand retention periods measured in years, not months.

Until now, OpenEFA customers needing long-term archiving had to rely on third-party solutions or manual exports. That created gaps in searchability, compliance reporting, and disaster recovery.

Email archiving solves this by bringing native long-term retention directly into the OpenEFA platform.

What's New

The Email Archiving add-on extends OpenEFA with these key capabilities:

Flexible Retention Periods

Configure retention from 1 to 7 years per domain, tailored to your compliance and business requirements.

Automatic Migration

Emails older than 90 days are automatically migrated from the active mail system to the dedicated archive server — no manual intervention required.

Compressed Storage

Archived messages are stored in a compressed format, significantly reducing storage costs over multi-year retention periods.

Full Searchability

Search archived emails by sender, recipient, subject, date range, or keywords — even across years of stored data.

Raw .eml Recovery

Retrieve original messages in standard .eml format for legal discovery, compliance audits, or forensic investigation.

Per-Domain Control

Enable archiving for specific domains with independent retention policies — giving you granular control across multi-domain environments.

Integrated with OpenEFA Scoring

Archived emails retain their original OpenEFA threat scores, module verdicts, and classification metadata for full audit trails.

How It Works

1
Enable Per Domain

Archiving is a configuration option enabled on a per-domain basis. Choose which domains require long-term retention and set the retention period (1–7 years).

2
Automatic Migration

Emails older than 90 days are automatically migrated from the active OpenEFA system to a dedicated archive server. The process runs in the background with no impact on mail flow.

3
Search & Recover

Access the archive interface to search, browse, and recover messages at any time. Export original .eml files for legal or compliance purposes.

Who It's For

Meet legal hold obligations and produce email evidence for discovery with full-text search and raw message export.
