 > In Postfix, when multiple recipients are specified in the `To:` field of an email, the Postfix policy delegation protocol (the `check_policy_service` action in this case) doesn't include each individual recipient separately by default. Instead, it sends a single `recipient=` line with an empty value to indicate that there are recipients but doesn't list them individually.
