One Platform

Enterprise Power Meets Modern Design.

Irsal gives you total ownership of your communication infrastructure on your own hardware — without sacrificing modern features like instant push, AI-driven spam filtering, multi-tenancy, and server-side threading.

Irsal MailServer

The Engine Room

Multi-tenant, lightning-fast Rust architecture, built-in telemetry, AI spam protection, and sharded storage scaling.

Irsal Webmail

The Interface

JMAP-native web interface for Mail, Calendar, Contacts, and Files with a slick, zero-lag user experience.

Features

Everything You Need. Nothing You Don't.

From AI spam filtering to instant push notifications — Irsal is built for teams that demand reliability.

Multi-Tenancy & Isolation

Host multiple organizations safely on a single deployment with isolated domains, user directories, and quotas.

AI Spam Filtering

Combine statistical classifiers, blocklists, and LLMs to analyze suspicious messages with automated triage.

Instant Push

Zero polling loops or 30-second IMAP delays. Changes are pushed instantly over a single TLS connection.

Sharded Storage

Scale effortlessly with S3/Azure/filesystem backends and sharded in-memory key-value stores.

Real-Time Telemetry

Live SMTP connection tracing, memory metrics, and customizable alerting webhooks down to the millisecond.

Masked Email & Privacy

Generate disposable masked email addresses to keep your main address private and prevent spam leaks.

Why Change

Email Is 50+ Years Old.
Your Webmail Doesn't Have to Be.

Legacy protocols require complex synchronization loops and heavy resource overhead. Irsal transitions your stack to JMAP — transforming email performance.

Legacy Mail (IMAP/PHP)

Irsal Platform (JMAP + Rust)

✗ 30-Second Polling

Constant battery drain & delayed inbox notifications.

✓ Instant Push

Server notifies the client in real-time over a single TLS connection.

✗ Multiple Roundtrips

Marking read, moving, and fetching requires separate IMAP requests.

✓ Batched Mutations

Multi-action operations bundled into a single JMAP request.

✗ Browser-Heavy Threading

Local JS reassembles conversations on every page load.

✓ Server-Side Threading

Threads are pre-computed natively inside Irsal MailServer.

✗ Slow, Cluttered UI

Outdated frameworks with heavy plugin dependencies.

✓ TypeScript & Next.js UI

Ultra-responsive client designed for 60fps performance.
