@@ -1,5 +1,7 @@
 This module allows adding domains to the mail domain blacklist to prevent Odoo from assuming  
 that users with the same domain belong to the same organization.
 
-Due to the nature of this module, in a multi-tenant setting, the configuration in one database
-affects all databases in the Odoo instance.
+The effect of blacklist domains depends on how the Odoo server is configured to
+load databases. In environments where multiple databases can be listed and
+accessed, blacklist entries apply across all of them. When the server loads only
+a single, explicit database, the blacklist affects only that database.
