Using Custom Email Aliases in Azure Communication Services (ACS)

If you’ve started experimenting with Azure Communication Services (ACS) Email, you’ve probably noticed a small but annoying limitation in the Azure Portal:
by default, you can only send emails from the DoNotReply@yourdomain.com address.

But what if you want to send newsletters from newsletter@yourdomain.com, or customer notifications from support@yourdomain.com?
Unfortunately, the Azure Portal doesn’t (yet) allow you to configure additional sender aliases.
