Documentation
GoEmail Services is the home of go-emailservice-ads, an MIT-licensed mail server written in Go, and mailscript, its filtering language and perimeter proxy. Together they run the mail for msgs.global in production. These docs describe how the software actually works, end to end.
Platform Guide
go-emailservice-ads end to end: the SMTP → queue → filter → store → IMAP pipeline, listeners and ports, the config schema, the admin CLIs, and the REST API.
mailscript
The filtering language and perimeter proxy: rule syntax, conditions and actions, deployment, and how it plugs into the platform's filter chains.
Two looks, one manual
Use the theme toggle in the header. Dark is the AfterDark house style. Light is the plain, classic mail-server look — paper, ink, and monospace — for people who want their MTA documentation to read like djb's or postfix.org, not a product launch. Same content either way.
