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. Run the installer. It asks for two things: your mail server’s hostname (detected for you where it can be) and an email address for TLS certificates. It generates every password and key itself.
2. Vectis builds and runs the whole mail stack (Postfix, Dovecot, Rspamd and Traefik) with every service config generated for you.
3. Add domains and mailboxes from the admin dashboard. They take effect immediately, with no restarts.
4. Manage the rest from the dashboard or the REST API: DKIM keys, backups, updates, and per-domain spam controls on Pro.
5. Prefer configuration as code? Advanced settings live in one readable config.yaml you can keep in version control and apply with a single command. You never have to touch it.
