Is there a way to determine what email address an email was sent to when an account has multiple secondary SMTP email addresses?

Hi there,

We have an account that we will be using that has 250 additional email addresses added to it.  Is there a way to determine what email address an email was sent to?  Currently, when an email is sent to one of the secondary addresses, it shows up as the main email address within outlook.

Thanks for your help!
