Ran into this today, it's something that is completely possible to do from the UI but not from terraform.
I was hoping that there would be a work-around of having separate "from" and "termination" domains but this doesn't seem to be possible either at the moment which makes it afik impossible to configure the from domain with terraform
This issue has been added to our internal backlog to be prioritized. Pull requests and +1s on the issue summary will help it move up the backlog (ref: DI-1325).
