DockFlare v3.1.0: You've Got Mail

[ChrispyBacon-dev]

[v3.1.0] - 2026-04-16

Cloudflare Context: Cloudflare's Email Service entered public beta today — the same send_email Workers binding that powers DockFlare Mail's outbound relay is now generally available. Read the announcement: Email for Agents

Added

• Sovereign Email Suite: A fully self-hosted email system that uses Cloudflare as a stateless delivery layer while keeping all email data local.
  • Inbound Processing: Automated setup of Cloudflare Email Routing, Workers, and R2 buckets for message ingestion.
  • Outbound Processing: Authenticated outbound relay via Cloudflare Workers and the send_email binding. Cloudflare handles SPF, DKIM, and DMARC automatically for authenticated delivery.
  • Local Data Sovereignty: All emails are stored in a local SQLite FTS5 database with attachments saved to a dedicated Docker volume. Cloudflare is a pipe, not a vault.
  • Mail Manager Service: A new backend service handling MIME parsing, R2 interaction, mailbox management, and a full REST API.
• PWA-Ready Webmail: A modern, installable Vue 3 + Vite + TypeScript webmail client.
  • Progressive Web App: Supports browser installation on desktop and mobile with a standalone display mode.
  • Desktop/Mobile Notifications: Background push notifications for new mail via Web Push (VAPID) and Service Workers.
  • Offline Support: App shell caching and a graceful offline fallback page.
  • Modern UI: 3-panel layout with folder navigation, message list, and rich message display using Shadcn/Vue and Tailwind CSS.
• Multi-Domain Email Support: Manage inbound and outbound email for an unlimited number of domains simultaneously.
  • Isolation: Complete isolation of secrets, R2 buckets, and Cloudflare Worker endpoints per domain.
  • Domain Registry: Dynamic synchronization of domain configurations from the Master to the Mail Manager.
  • Domain-Aware Webhooks: Inbound webhook routing correctly identifies domains via custom headers and verifies signatures with domain-specific secrets.
• Automated Infrastructure Provisioning:
  • One-Click Setup: Provision all required Cloudflare resources (Email Routing, Workers, R2, DNS) directly from the DockFlare UI.
  • DNS Repair Tool: A new "Repair DNS" feature to re-apply or fix missing MX, SPF, DMARC, and DKIM records.
  • Worker Redeployment: Easily push updates or configuration changes to Cloudflare Workers from the UI.
• Advanced DNS & DKIM:
  • Authoritative DKIM Handling: Automatically fetches and applies DKIM TXT records generated by Cloudflare.
  • Zone-Aware Placement: Smart placement of email-related DNS records across multiple Cloudflare zones.
• Per-Mailbox Storage Quotas: Quota enforcement at the Cloudflare KV layer — messages are rejected at the edge before reaching the server when a mailbox is full. Quota configuration and current usage are visible in the mailbox management UI.
• Backup & Restore: Full backup and restore of the mail database and data volume, with teardown options (including complete wipe of local data and Cloudflare resources) available from the Email section.
• Security & Performance:
  • EdDSA JWT Authentication: Secure Ed25519 key pair-based communication between Webmail, Mail Manager, and Master.
  • Outbound Rate Limiting: Built-in per-sender rate limiting (50/hour, 200/day) enforced at the Worker layer.
  • FTS5 Search: Full-text search across all mailboxes for fast email discovery.
  • CVE Scan & Dependency Refresh: Full dependency audit included in this release.

Changed

• Navigation: Added "Email" as a primary navigation item in the Master UI.
• Login Flow: Added a "Login to Email" shortcut on the main login page when email services are configured.
• Docker Compose: Updated to include dockflare-mail-manager and dockflare-webmail services with a shared email profile — opt-in, no impact on existing setups.

Notes

• Email services are fully opt-in. Existing installations are unaffected unless the email profile is added to the Compose configuration.
• Documentation for setup, DNS requirements, and required Cloudflare API permissions is available at dockflare.app.
