I would have a failsafe, like use a major email provider for emails that you need to go through for like work order government stuff.
Hosting your own email is a great learning experience and is fun to do; but your emails will get marked as spam, you’ll have to constantly perform maintenance, and have major reliability issues.
Most of the issues youll have are fine for personal use, but is dicey if you plan to migrate 100%
Edit: receiving email is less of an issue of sending. The forwarder should be reliable, however, its the sending from the forwarding address that would possibly be an issue.
