## What it is
Modoboa is an open-source mail hosting and management platform with a modern web UI, built in Python/Django and Vue. It integrates Postfix, Dovecot, and Rspamd behind an administration panel, webmail, calendar, and address book.

## Use cases
- self-host my own email server
- manage multiple mail domains and mailboxes from a web panel
- replace Gmail with a private mail server
- set up webmail, calendar, and address book for my domain
- manage DKIM, DMARC, and spam filtering for my mail server
- offer mail hosting to customers with per-domain admin accounts

## When to choose
- you want a full self-hosted mail stack (SMTP, IMAP, webmail) managed from one UI
- you need multi-domain, multi-admin mail hosting on your own Linux server
- you value open source and data independence from email providers

## When to avoid
- you only need a transactional email API for sending mail from apps
- you cannot run and maintain a Linux server with proper DNS records
- you need a lightweight MTA-only solution without a web interface

## Facets
- artifact type: application
