Hello,
It is highly recommended for production servers to use a publicly
accessible FQDN (for example: openwisp2.mydomain.com) as the hostname in
the Ansible inventory file. This is needed to send emails properly.
If you are installing for development, you can bypass this error by adding
postfix_myhostname:
localhost as one of the vars in playbook.yml.
Regards,
Daniel
