How to bind the account to a particular recipient?

There are two accounts, internal and external. You need to configure so that the internal account was sent to the internal address , and external sent to an external address . And then we have to send reports to each recipient separately, creating a message.
Don't know how to do it but that would the program know which account to send email to a specific recipient
