# Role `send_only_mail_server`

Makes sure a send-only mail server is deployed using OpenSMTPD and Rspamd for DKIM signing.

Make sure to manually set a DMARC record and MX record for the mail domains.

## Supported Distributions

The following distributions are supported:

- Debian 11

## Required Arguments

For the required arguments look at the [`argument_specs.yaml`](./meta/argument_specs.yml)

Also make sure to set the following for the `cert` role dependency:

- `cert__acme_account_email`

## Updates

This role doesn't handle updates.
However it uses the system package manager for installing all the packages, so when you're making sure the system packages are up-to-date, you're handling updates for the packages installed by this role as well.

## `hosts`

The `hosts` for this role need to be the machines on which you want to deploy a mail server.
