Finish Mail Server Configuration

A send only Postifx instance is setup up during play/main.

DNS records for DKIM, SPF and DMARC are automatically added via Hetzner DNA API but you should check and test that these have been set up correctly.

The DMARC DNS record directs DMARC reports to the address you configure for postfix_email_recipient — you will need to configure a DNS record on that domain to authorize receipt of DMARC reports.

A a backup of the generated DNS DKIM text record is also downloaded to local/fetched/YOURSERVER/etc/dkimkeys/default.txt.

Lastly you should add a reverse DNS record for the mail server. See Hetzner Docs for how to add this per server.
