Wei S. e5e119528f V0.5.0 release (#335)
* adding exports to backend package, page icons update

* Integrity report PDF generation

* Fixed inline attachment images not displaying in the email preview by modifying `EmailPreview.svelte`.
The email HTML references embedded images via `cid:` URIs (e.g., `src="cid:ii_19c6d5f8d5eee7bd6d91"`), but the component never resolved those `cid:` references to actual image data, even though `postal-mime` already parses inline attachments with their `contentId` and binary `content`.
The `emailHtml` derived value now calls `resolveContentIdReferences()` before rendering, so inline/embedded images display correctly in the iframe preview.

* feat: strip non-inline attachments from EML before storage

Add nodemailer dependency and emlUtils helper to remove non-inline
attachments from .eml buffers during ingestion. This avoids
double-storing attachment data since attachments are already stored
separately.

* upload error handing for file based ingestion

* Use Postgres for sync session management

* Google workspace / MS 365 duplicate check, avoid extra API call when previous ingestion fails

* OpenAPI specs for API docs

* code formatting

* ran duplicate check for IMAP import, optimize message listing

* Version update

Get Started 👋

Welcome to Open Archiver! This guide will help you get started with setting up and using the platform.

What is Open Archiver?

A secure, sovereign, and affordable open-source platform for email archiving and eDiscovery.

Open Archiver provides a robust, self-hosted solution for archiving, storing, indexing, and searching emails from major platforms, including Google Workspace (Gmail), Microsoft 365, as well as generic IMAP-enabled email inboxes. Use Open Archiver to keep a permanent, tamper-proof record of your communication history, free from vendor lock-in.

Key Features

  • 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. The system uses deduplication and compression to minimize storage costs. All data is encrypted at rest.
  • Pluggable Storage Backends: Support both local filesystem storage and S3-compatible object storage (like AWS S3 or MinIO).
  • Powerful Search & eDiscovery: A high-performance search engine indexes the full text of emails and attachments (PDF, DOCX, etc.).
  • Compliance & Retention: Define granular retention policies to automatically manage the lifecycle of your data. Place legal holds on communications to prevent deletion during litigation (TBD).
  • Comprehensive Auditing: An immutable audit trail logs all system activities, ensuring you have a clear record of who accessed what and when (TBD).

Installation

To get your own instance of Open Archiver running, follow our detailed installation guide:

Data Source Configuration 🔌
