Base setup for a Debian server. Basic safety included, so it can be put on the internet right away.
See defaults/main.yml for variables and their defaults.
For outbound emails to work, variables have to be set differently, according to weather the server's hostname / fqdn is excepted by outbound mail servers as sender fqdn or not:
If it is accepted:
base__hostname: <hostname>base__host_fqdn: <hostname.domain>- do not set
base__external_fqdn
If it's not accepted, but there is another "external" fqdn which can be used instead:
base__hostname: <internal_hostname>base__external_fqdn: <fqdn_accepted_by_outbound_servers>- may or may not be set:
base__host_fqdn
