The cosmos generator linked a consumer to its provider only through an '<role>' in group_names reference or an explicit provides: name. A hard dependency has neither -- pinning the provider on unconditionally is exactly what removes the Jinja reference the generator was reading -- so web-svc-asset's bond to web-svc-file vanished from the diagram the moment it became binding. Match a service key against the provider's own primary key from the registry, in both directions. Services the role turns off drew a solid 1:1 edge, claiming a mandatory relationship for something that carries nothing at deploy time. They now render as a red 0..0 edge; edge merging gained a real precedence so a provider consumed through two keys stays live when only one is off. Named colour, not hex: a '#' opens an entity code in the mermaid lexer and turns the whole diagram into a parse error on GitHub. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

# msmtp
|
|
|
|
## Description
|
|
|
|
This Ansible role installs and configures **msmtp** (plus optional sendmail compatibility) across the default Infinito distro set: Arch Linux, Debian, Ubuntu, Fedora and CentOS. It provides a lightweight SMTP client that serves as a drop-in replacement for traditional sendmail workflows, enabling reliable email delivery via an external SMTP server. For more background on SMTP, see [SMTP on Wikipedia](https://en.wikipedia.org/wiki/SMTP).
|
|
|
|
## Overview
|
|
|
|
The role installs **msmtp**, handles distro-specific package differences (including EPEL bootstrap on EL-family hosts when required), and deploys a pre-configured `msmtprc` file via Jinja2. For distros without a dedicated `msmtp-mta` package, it configures a direct `/usr/bin/sendmail` compatibility symlink to `msmtp`.
|
|
|
|
## Cosmos
|
|
|
|
The diagram places msmtp in the Infinito.Nexus cosmos: the components it deploys (capabilities), the central services it consumes (dependencies), and its outward reach (federation and bridged external networks).

end
|

```
|
|
|
|
Solid `1:1` edges are fixed relationships; dashed `0..1` edges are conditional (enabled only in matching deployments); red `0..0` edges are turned off in this role. Node markers show the role's deploy modes (💻 host, 🐳 compose, 🐝 swarm); ❌ marks a service that is explicitly turned off, and ⚙️ an Ansible role dependency declared in `meta/main.yml`.

|
## Purpose
|
|
|
|
The purpose of this role is to automate the setup of a lightweight SMTP client that acts as a sendmail replacement. By configuring msmtp, the role facilitates direct email sending using your SMTP server credentials, making it a simple yet effective solution for system notifications and other email-based communications.
|
|
|
|
## Features
|
|
|
|
- **Installs msmtp cross-distro:** Uses distro-aware package handling for Arch, Debian, Ubuntu, Fedora, and CentOS.
|
|
- **Handles sendmail compatibility:** Installs `msmtp-mta` where available, otherwise provisions a compatible sendmail symlink.
|
|
- **Customizable SMTP Configuration:** Deploys a customizable msmtprc configuration file with parameters for TLS, authentication, and server details.
|
|
- **Drop-in sendmail Replacement:** Configures msmtp to serve as the default sendmail command.
|
|
- **Idempotent Setup:** Ensures the tasks run only once with internal flagging.
|
|
- **Integration Ready:** Easily integrates with other system roles within the Infinito.Nexus environment for automated notifications.
