Postfix mail server¶
Each VM installed via Ansible is able to send emails from the enough.community domain.
Postfix mail relay¶
A mail relay based on Postfix is defined on the host postfix-host, via the playbook molecule/postfix/postfix-relay-playbook.yml, based on the Postfix DebOps role.
It is configured as an open relay using smtps. The relaying restrictions are set in firewall using OpenStack.
