Maddy is a composable all-in-one mail server written in Go that combines an SMTP MTA/MX, IMAP storage, and email security protocols (DKIM, SPF, DMARC, DANE, MTA-STS) in a single daemon. It replaces the traditional Postfix + Dovecot + OpenDKIM stack with one lightweight, uniformly configured binary.
Use cases
- self-host a personal email server on a VPS
- run an SMTP server to send and receive mail
- host an IMAP mailbox server
- sign outgoing mail with DKIM and enforce SPF/DMARC
- replace Postfix and Dovecot with a single lightweight daemon
- set up a small mail server without Docker
When to choose
- you want a minimal, single-binary mail server for a small personal or low-volume domain
- you prefer uniform configuration over stitching together Postfix, Dovecot, and OpenDKIM
- you want a memory-safe Go implementation that doesn't need root
- you have limited resources (about 1 GiB RAM is enough)
When to avoid
- you need a mature, feature-packed IMAP server - Dovecot is more battle-tested
- you want a web admin interface or a full groupware bundle like MailCow or Mail-in-a-Box
- you run a large, high-volume mail operation needing 20-year-old proven software
- your provider blocks outbound port 25 and you can't use a smart host
