Ansible Role: postfix

DISCLAIMER

After this announcement I will not test on RHEL anymore.

This role install postfix and configure it to use a remote mail relay.

Requirements

To send mails you need access to a remote mail relay (such as Gmail).

Role Variables

postfix_remote_host: a.remote.host  # smtp.gmail.com
postfix_remote_port: 587
postfix_remote_user: username  # [email protected]
postfix_remote_password: password  # application password if 2FA is enabled

These are the variables used to establish a connection with the remote relay server and must be provided in the playbook.

postfix_config:
  - name: relayhost
    value: '[{{ postfix_remote_host }}]:{{ postfix_remote_port }}'
  - name: smtp_use_tls
    value: 'yes'
  - name: smtp_sasl_auth_enable
    value: 'yes'
  - name: smtp_sasl_security_options
    value:

    value: hash:/etc/postfix/sasl/sasl_passwd
  - name: inet_interfaces
    value: localhost
  - name: inet_protocols
    value: ipv4

This is an array with the needed configuration options to add to the /etc/postfix/main.cf file.

Testing with molecule (including the docker images used) is stolen from heavily inspired by Jeff Geerling. Watch his video (and the other ones as well).
