    Goal: Redact Sensitive Data prior to sharing.

    • This function fixEmailDomains will fix email domains by ensuring only a top level domain is used.

    • Example given an Email address like jack.smith@mailhost.company.com we update it to use only the top level domain jack.smith@company.com.

    • Requires Eventing Storage (or metadata collection) and a "source" collection.

    • Will operate on all documents where doc.type === "employees".
