improvmx.com has a free tier.
How to do it yourself:
The simplest way to do this in my opinion is to get a hosting package somewhere with unlimited domains. Can be some shared host somewhere. In the cPanel of the hosting you can create a "Catch All Email" address. All the emails for the domain will then be forwarded.
Then you just have to change the MX servers to the new host and done.
gotcha! thank you
