# [Ansible role postfix](#postfix)
Install and configure postfix on your system.

## [Example Playbook](#example-playbook)
This example is taken from [`molecule/default/converge.yml`](https://github.com/robertdebock/ansible-role-postfix/blob/master/molecule/default/converge.yml) and is tested on each push, pull request and release.
```yaml
---
- name: Converge
hosts: all
become: true
gather_facts: true
roles:
- role: robertdebock.postfix
# postfix_relayhost: "[relay.example.com]"
postfix_myhostname: "smtp.example.com"
postfix_mydomain: "example.com"
postfix_myorigin: "example.com"
postfix_mynetworks:
- 127.0.0.0/8
- 192.168.0.0/16
postfix_aliases:
- name: root
destination: [email protected]
# Ziggo settings: ("email-address" and "email-password" are placeholders)
postfix_relayhost: "[smtp.ziggo.nl]:587"
postfix_smtp_sasl_auth_enable: true
postfix_smtp_sasl_password_map: "/etc/postfix/relay_pass"
postfix_smtp_sasl_security_options: ""
postfix_smtp_tls_wrappermode: false
postfix_smtp_tls_security_level: may
postfix_smtp_sasl_password_map_content: |
[smtp.ziggo.nl]:587 email-address:email-password
```
The machine needs to be prepared. In CI this is done using [`molecule/default/prepare.yml`](https://github.com/robertdebock/ansible-role-postfix/blob/master/molecule/default/prepare.yml):
```yaml
---
- name: Prepare
hosts: all
become: true
gather_facts: false
roles:
- role: robertdebock.bootstrap
- role: robertdebock.core_dependencies
```
Also see a [full explanation and example](https://robertdebock.nl/how-to-use-these-roles.html) on how to use these roles.
## [Role Variables](#role-variables)
The default values for the variables are set in [`defaults/main.yml`](https://github.com/robertdebock/ansible-role-postfix/blob/master/defaults/main.yml):
