This document will provide the steps necessary to set up custom domain authentication for the email service provider, Emma, approving Emma to send DMARC-compliant email from addresses in your organization's subdomain (e.g. mydomain.wisc.edu).

Information about the protection of UW-Madison email with DMARC can be found here: Email Authenticity

Note: approving a third-party email vendor to send email as/from @wisc.edu addresses (e.g. mynetid@wisc.edu) is not permitted. Only approve third-party email vendors to send email as/from addresses in your subdomain (e.g. account@mydomain.wisc.edu).
