🔐 Security first
FIPS-aligned crypto, no SHA-1. PBKDF2-SHA256 passwords, TOTP, and passkeys gated behind your password.
Your entire mail platform.
One beautiful app.
A complete, self-hosted email server — SMTP, IMAP4, POP3 and Exchange ActiveSync — with a modern webmail, a powerful control center, DKIM signing, passkeys and TOTP. No database. Just files you own.
📬 Every protocol
SMTP (with STARTTLS & DKIM), IMAP4rev1, POP3, and Microsoft Exchange ActiveSync for mobile.
🗂️ No database
Mail, accounts and configuration live as folders and JSON files you can back up, inspect and move.
📱 Installable PWA
The webmail installs like a native app, works offline-aware, and adapts to any screen.
🌍 Cross-platform
Runs on Windows Server 2022+, Linux and macOS on .NET 10 — and sits happily behind any reverse proxy.
⚙️ Full control
Manage domains, users, quotas and DKIM keys from a responsive web control center.
