Install and configure postfix on your system.

Example Playbook
|
|
----------------
|
|
|
|
This example is taken from `molecule/resources/playbook.yml` and is tested on each push, pull request and release.
|
|
```yaml
|
|
---
|
|
- name: Converge
|
|
hosts: all
|
|
become: yes
|
|
gather_facts: yes
|
|
|
|
vars:
|
|
postfix_aliases:
|
|
- name: root
|
|
destination: robert@meinit.nl
|
|
|
|
roles:
|
|
- robertdebock.postfix
|
|
```
|
|
|
|
The machine you are running this on, may need to be prepared, I use this playbook to ensure everything is in place to let the role work.
|
|
```yaml
|
|
---
|
|
- name: Prepare
|
|
hosts: all
|
|
become: yes
|
|
gather_facts: no
|
|
|
|
roles:
|
|
- robertdebock.bootstrap
|
|
- robertdebock.core_dependencies
|
|
```
|
|
|

Role Variables
|
|
--------------
|
|
|
|
These variables are set in `defaults/main.yml`:

```yaml
|

# defaults file for postfix
|
|
|
|
# These settings are required in postfix.
|
|
postfix_myhostname: "{{ ansible_fqdn }}"
|
|
postfix_mydomain: "{{ ansible_domain | default ('localdomain', true) }}"
|
|
postfix_myorigin: "{{ ansible_domain | default ('localdomain', true) }}"
|
|
|
|
# To "listen" on public interfaces, set inet_interfaces to something like
|
|
# "all" or the name of the interface, such as "eth0".
|
|
postfix_inet_inferfaces: "loopback-only"
|
|
|
|
# The distination tells Postfix what mails to accept mail for.
|
|
postfix_mydestination: $mydomain, $myhostname, localhost.$mydomain, localhost
|
|
|
|
# To accept email from other machines, set the mynetworks to something like
|
|
# "192.168.0.0/24".
|
|
postfix_mynetworks: "127.0.0.0/8"
|
|
|
|
# These settings change the role of the postfix server to a relay host.
|
|
# postfix_relay_domains: "$mydestination"
|
|
|
|
# If you want to forward emails to another central relay server, set relayhost.
|
|
# use brackets to sent to the A-record of the relayhost.
|
|
# postfix_relayhost: [relay.example.com]
|
|
|
|
# Set the restrictions for receiving mails.

|
# To enable spamassassin, ensure spamassassin is installed,
|

# postfix_spamassassin: enabled
|
|
# postfix_spamassassin_user: spamd
|
|

# To enable clamav, ensure clamav is installed,
|

# (hint: role: robertdebock.clamav) and set this variable:

|
# You can configure aliases here. Typically redirecting `root` is a good plan.
|
|
# postfix_aliases:

Testing
|
|
-------
|
|
|
|
[Unit tests](https://travis-ci.org/robertdebock/ansible-role-postfix) are done on every commit, pull request, release and periodically.
|
|
|
|
If you find issues, please register them in [GitHub](https://github.com/robertdebock/ansible-role-postfix/issues)
|
|
|
|
Testing is done using [Tox](https://tox.readthedocs.io/en/latest/) and [Molecule](https://github.com/ansible/molecule):
|
|
|
|
[Tox](https://tox.readthedocs.io/en/latest/) tests multiple ansible versions.
|
|
[Molecule](https://github.com/ansible/molecule) tests multiple distributions.
|
|
|
|
To test using the defaults (any installed ansible version, namespace: `robertdebock`, image: `fedora`, tag: `latest`):
|
|
|
|
```
|
|
molecule test
|
|
|
|
# Or select a specific image:
|
|
image=ubuntu molecule test
|
|
# Or select a specific image and a specific tag:
|
|
image="debian" tag="stable" tox
|
|
```
|
|
|
|
Or you can test multiple versions of Ansible, and select images:
|
|
Tox allows multiple versions of Ansible to be tested. To run the default (namespace: `robertdebock`, image: `fedora`, tag: `latest`) tests:
|
|
|
|
```
|
|
tox
|
|
|
|
# To run CentOS (namespace: `robertdebock`, tag: `latest`)
|
|
image="centos" tox
|
|
# Or customize more:
|
|
image="debian" tag="stable" tox
|
