FanMail
A self-hosted, Persian-first enterprise email service at 10,000-user scale — a sovereign alternative to IceWarp and Exchange.
FanMail is a fully self-hosted enterprise email platform built on the open-source Stalwart Mail Server, designed to run entirely on-premises with no foreign cloud dependency. It pairs a modern, conversation-based webmail (JMAP, not legacy IMAP) with a built-in admin panel — at a fraction of the cost of commercial suites.
Proven at 10,000-user scale as a replacement for IceWarp, it targets under 200M Tomans/year of operating cost versus ~3B before. Two local-market advantages: SMS one-time-password login (and 2FA), and opt-in Email-to-SMS notifications.
