When syncing from AD fill in email address from AD(email address)

[Nomad]

Currently when syncing a user with Active Directory, the email field is filled in by the AD(userPrinicpalName) field. This doesn't make since. The email addresses in our organization and the userPrincipal name are not the same. If they filled in the email address with the AD(email) field wouldn't that make more since, and guarantee that the email field gets filled in with the correct information?
