The value of the domain name is automatically chosen as the postfix
hostname and since you are using an ip address instead of a domain name,
postfix complains, so you have to tell postfix to use "localhost" instead
of 10.0.0.44, you can do by modifying your playbook so it looks like the
following:
- hosts: openwisp2
become: "{{ become | default('yes') }}"
roles:
- openwisp.openwisp2
vars:
postfix_myhostname: "localhost"
