Per defaults/main.yml this role expects both a recipient e-mail address and login credentials for an SMTP mail submission server to be available in a HashiCorp Vault instance. Feel free to override these variables as needed with host or group vars. If you stick with HashiCorp Vault the default path for SMTP credentials is settings/comms/e-mail/default/sender, the default path for a recipient address is settings/comms/e-mail/default/recipient.

Sender data

addr-spec: Your sender e-mail address rendered as an RFC 2822 addr-spec string such as noreply@example.com.
credentials-password-sasl-smtp-auth-login: A password that Postfix will use to log in to the SMTP mail submission server via the AUTH LOGIN SMTP SASL authentication mechanism.
credentials-username: The SMTP username needed to log in to the SMTP mail submission server.
submission-server-fqdn: Your upstream SMTP mail submission server's fully qualified domain name such as smtp.example.com.
submission-server-port: The TCP port you want Postfix to use to connect to the SMTP mail submission server.

Recipient data

addr-spec: Same as above, a recipient e-mail address rendered as an RFC 2822 addr-spec string such as noreply@example.com.
