SOQL support for multi-employee Mule applications

Question

I have been working on Mule for a couple of months and understand how Mule and load balancing work if I manage to get to the http endpoint. However, one use case is where I used the Salesforce connector and wrote SOQL to get updates on any object (say, Account). The problem is when the update is performed in the Salesforce Object, it brings the update message to all three employees. This may be due to some coding on the application side in order to drop the other two messages, but I am looking to see if there is a solution from the mailbox where exactly one message was received only to one employee, and not to all three. Appreciate your answer.
