Vectis Mail Server

A self-host mail server built on Postfix, Dovecot, and Rspamd, with a REST API and admin UI on top. One YAML config; the orchestrator handles atomic updates, rollback, and per-service reloads.

Built for operators who want the underlying mail stack (no reinventing) but a modern operator surface (no manual config tweaking).

If you're choosing between Vectis Mail, Mail-in-a-Box, and Mailcow — they all sit in the same self-host mail niche with different trade-offs. Vectis prioritises declarative config and a REST API; the others prioritise install simplicity (MIAB) and admin-UI maturity (Mailcow).

What's in the box

• Mail stack: Postfix, Dovecot, Rspamd; DKIM/SPF/DMARC out of the box.
• Admin UI: React + TypeScript dashboard for domains, mailboxes, aliases, deliverability, audit log, backups, and updates.
• API: authenticated REST endpoints for everything in the UI plus outbound sending (single + batch), inbound webhooks, and analytics.
• Webmail: Roundcube with a Vectis skin and ManageSieve filter rules.
• Update orchestrator: plan / apply / rollback rolling updates from the admin UI; atomic compose + image swaps.
• Backups: encrypted archives, scheduled or on-demand, with one-click restore from the admin UI.
• Monitoring: built-in Prometheus + Grafana + Loki.
• TLS: automatic via Traefik + acme.sh.

Install

On a fresh Ubuntu 22.04+ VPS with port 25 unblocked and a PTR record pointed at the host:

curl -fsSL https://dl.vectismail.com/latest/install.sh | sudo bash

(Or download install.sh first and inspect it — see the installation walkthrough for the full step-by-step.)

The installer provisions Postgres, Valkey, Postfix, Dovecot, Rspamd, Traefik, the orchestrator, and the API container. Pre-flight checks verify DNS, port 25 reachability, hostname/PTR alignment, and disk space before any container starts.
