When searching for messages in the Message Audit Log (MAL) from the Control Center Status > Message Audit Logs page, the results contain more than the expected sender or recipient depending on the query. For instance, searching for all messages with recipeint [email protected] will show You the messages from [email protected] but also from [email protected] as the keyword [email protected] can be found on both.
This is expected based on the operation of Message Audit Logging and search engine.
Check out only the MAL records for the desired sender or recipient. For more details about message audit logs refer to the documentation.
