Key Features
A Reliable Open Source Email Archiver
Our email archiver is open source and built to be a dependable, long-term home for your communication data. From ingestion to storage and eDiscovery, every component of this email archiving software is designed for security and efficiency. It's the email archive open source solution you've been looking for.
- Universal Ingestion
- Connect to Google Workspace, Microsoft 365, and standard IMAP servers to perform initial bulk imports and maintain continuous, real-time synchronization.
- Secure & Efficient Storage
- Emails are stored in the standard `.eml` format, with deduplication and compression to minimize storage costs. AES-256 encryption at rest is available in the Enterprise Edition.
- Powerful Search & eDiscovery
- A high-performance full-text search engine indexes the full text of emails and attachments (PDF, DOCX, etc.), allowing for instant retrieval of any communication.
- Role-based Access Control
- Assign roles to users with limited access to resources. Create roles for end users and third-party auditors. We implement an AWS IAM-style policy system to realize fine-grained access control.
Data Sovereignty
Your Self-Hosted Mail Archive
With Open Archiver, you decide where your mail archive is stored. Avoid vendor lock-in and ensure your sensitive communication history remains under your control with our self-hosted email archive solution. It's the ideal open source email backup.
- Pluggable Storage Backends
Choose between local filesystem storage for simplicity or any S3-compatible object storage (like AWS S3 or MinIO) for scalability and resilience.
- Compliance & Retention (Coming soon)
Define granular retention policies to automatically manage the lifecycle of your data and place legal holds on communications to prevent deletion during litigation.
- Comprehensive Auditing (Coming soon)
An immutable audit trail logs all system activities, ensuring you have a clear record of who accessed what and when for security and compliance purposes.
