Features Overview

Mailyte packs a lot into one box. This page gives you a bird's-eye view of every feature, where it lives, and how ready it is for production use. Ports listed are the host-published ports from docker-compose.yml; in production every non-mail port is bound to loopback and public traffic goes through Traefik on 443.

In this section

  • Email Tracking

    Pixel opens and click tracking injected by a Postfix content filter — know what happens after you hit send.

How features connect

Most features talk to each other through the shared webhook dispatcher, the Postfix content filter, and the shared database:
