+`check-program`: Introduced as a flag for global or source options.
+
+By default, this flag is set to false. Enabling the check-program flag triggers `program` name validation for `RFC3164` messages. Valid `program` names must adhere to the following criteria:
+
+Contain only these characters: `[a-zA-Z0-9-_/().]`
+Include at least one alphabetical character.
+If a `program` name fails validation, it will be considered part of the log message.
+
+
+Example:
+
+```
+source { network(flags(check-hostname, check-program)); };
+```
