Most self-hosted mail solutions feel like 2008 because they were written then. Irsal transitions your stack to JMAP — transforming email performance from the ground up.
IMAP and PHP-based webmail require complex synchronization loops and heavy resource overhead. Every action costs a round trip. Every inbox load costs a rebuild.
Constant battery drain and delayed inbox notifications. Your client has no idea an email arrived until it asks.
Server notifies the client in real-time over a single persistent TLS connection. No polling. No delay.
Marking read, moving a message, and fetching the next email each require separate IMAP requests.
Multi-action operations bundled into a single JMAP request. One trip. Everything done.
Local JavaScript reassembles conversations on every single page load, burning CPU and time.
Threads are pre-computed natively inside Irsal MailServer. The client just renders what's ready.
Outdated frameworks with heavy plugin dependencies built for a browser landscape that no longer exists.
Ultra-responsive client designed for 60fps performance on modern hardware and browsers.
JMAP is the modern, open standard for email synchronization. It was designed to fix everything IMAP got wrong.
All operations — fetch, update, delete, move — happen in one batched HTTP call. No persistent socket management required.
EventSource or WebSocket push means your inbox updates the moment a message arrives — no polling interval needed.
No server-side session state means horizontal scaling is trivial. Add nodes without complex session affinity configuration.
Migration from legacy mail servers is straightforward. Our engineering team can guide you through every step.
