About 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.
