I have the same problem. After running a sudo mailinabox, I ran into the same error!
Here is the feedback in copy:
FAILED: pip3 install email_validator>=1.0.0

I can access the web admin interface, but the checks fails and returns with the message: Something went wrong.
I tried to rerun the “mailinabox” setup again, but I’m still getting the same error. I tried to figure out to fix the single error of the email validator, but no chance! I need to get this back running. Please help us!
