Webmail & Mail Server Built for the Modern Era.
Email turned fifty. Irsal brings your entire email ecosystem into the decade we're actually in — combining a high-performance Rust mail server with an ultra-fast JMAP webmail client.
Everything You Need. Nothing You Don't.
Instant Push
Zero polling. Server notifies the client in real-time over a single TLS connection.
