What is it?

PMail is a self-hosted email server aimed at a minimal deployment process and low resource use. It ships as a single binary that includes send and receive mail services along with a web interface for managing mailboxes, so you can run mail for your own domain without assembling several separate components.

The server supports DKIM and SPF signing and checks, and it can obtain and renew Let's Encrypt certificates through ACME. It supports multiple domains and multiple users, and it works with any standard mail client over POP3, SMTP and IMAP. Configuration is handled through a bootstrap page in the browser, and the data store can be SQLite or MySQL. Plugins run as separate processes and can add features such as spam blocking or push notifications.

The project is written in Go with a Vue 3 and Element Plus frontend. Running it requires a server, a domain name, and open mail ports (25, 110, 143-related IMAP 993, 465, 587, 995), and the README recommends checking your IP against blocklists before deploying.
