Revert "switch email to something we already have in WIF"

This reverts commit 549c2e5.

We *should* be able to impersonate the non-WIF service account bc the
service account we're authed in as has Service Account User on the
target service account. But, our principal didn't have the View Service
Account role so maybe that was causing this "no service acct found"
error.
