What is Maddy?

A one-binary mail server learning to behave like production infrastructure.

maddy is an all-in-one SMTP and IMAP server written in Go, aimed at people who want a working mail host without assembling Postfix, Dovecot and a policy daemon themselves. The 0.9 line moved quickly — 0.9.0 through 0.9.5 between late March and late May — with the sequence following a recognisable shape: a feature release, an immediate patch for a broken integration, a security release, then cleanup. Configuration is directive-based, and much of the changelog concerns the behaviour of individual modules like auth.ldap, check.rspamd and check.dnsbl.

What is Superhuman?

Superhuman is becoming the email layer for AI agents, not just the fastest email client.

Superhuman has reached cross-platform parity with a complete mobile redesign and expanded its AI footprint substantially. Auto Drafts 2.0 now draws from inbox, calendar, and web context to produce drafts that users send unedited 60% of the time. The MCP integration exposes all connected Gmail and Outlook accounts to Claude, ChatGPT, and other agents simultaneously.

A one-binary mail server learning to behave like production infrastructure.

◆ Current state

maddy is an all-in-one SMTP and IMAP server written in Go, aimed at people who want a working mail host without assembling Postfix, Dovecot and a policy daemon themselves. The 0.9 line moved quickly — 0.9.0 through 0.9.5 between late March and late May — with the sequence following a recognisable shape: a feature release, an immediate patch for a broken integration, a security release, then cleanup. Configuration is directive-based, and much of the changelog concerns the behaviour of individual modules like auth.ldap, check.rspamd and check.dnsbl.

◆ Where it's heading

The project is systematically removing the compromises that made early versions convenient. Obsolete SASL LOGIN was disabled by default, the STARTTLS plaintext fallback was dropped, the maddyctl symlink behaviour and the implicit run command were deleted after four years of deprecation warnings, and libdns providers that have not kept up with 1.x are being cut. Running the other way is operational maturity: no-downtime config reload, queue-length metrics, OpenMetrics fixes, systemd readiness reporting, and SLSA build attestations on release artifacts. This is a project moving from hobbyist-friendly to operator-friendly, and accepting breakage to get there.

◆ Prediction

0.10.0 is already scoped by the deprecations announced in 0.9.1 — expect the flagged libdns providers to be removed and gandi to require Bearer tokens. Given the 0.9.x pattern, a feature release followed quickly by an integration fix is the likely shape.

S5.0

Superhuman is becoming the email layer for AI agents, not just the fastest email client.

◆ Current state

Superhuman has reached cross-platform parity with a complete mobile redesign and expanded its AI footprint substantially. Auto Drafts 2.0 now draws from inbox, calendar, and web context to produce drafts that users send unedited 60% of the time. The MCP integration exposes all connected Gmail and Outlook accounts to Claude, ChatGPT, and other agents simultaneously.

◆ Where it's heading

The product is converging on a model where Superhuman acts as the intelligent intermediary between users and their email — whether the user is driving it directly or delegating to an AI agent. Outlook category support and Gmail label sync for drafts extend this to more of the enterprise email surface. The direction is less about speed and more about AI-augmented inbox ownership.

◆ Prediction

The next move is likely deeper agentic capability: scheduled tasks, autonomous triage, or proactive send — going beyond drafting into taking action without the user in the loop.
