Introduction

Vectis Mail is a containerised, self-hosted email platform. It packages Postfix, Dovecot, Rspamd, Traefik, Postgres, and Valkey into a single deployment managed through one configuration file and a REST API.

Who is Vectis Mail for?

• Developers who need a transactional email API they control (replacing Sendgrid, Postmark, SES)
• SaaS operators who need inbound email processing via webhooks
• Sysadmins who want a modern alternative to Mailcow or iRedMail
• Organisations that require self-hosted email for compliance or data sovereignty

What you get

Component	Purpose
Postfix	Inbound/outbound SMTP, virtual domain hosting
Dovecot	IMAP/POP3, LMTP delivery, ManageSieve filters
Rspamd	Spam filtering, DKIM signing, greylisting
Traefik	Reverse proxy, automatic TLS, rate limiting
Postgres	All state — domains, mailboxes, aliases, config
Valkey	Sessions, caching, abuse detection counters
Admin UI	Web dashboard for managing everything
REST API	Programmatic control over all features
Orchestrator	Atomic updates with snapshot/rollback

How it works

1. You write a config.yaml describing your mail server
2. Vectis generates all service configs (Postfix, Dovecot, Rspamd, Traefik)
3. Docker Compose runs the full stack
4. Domains and mailboxes are stored in Postgres — no reload needed for changes
5. The admin UI and API give you full control
