Mail stopped working under 11.2
As soon as I updated to 11.2 my Mail app stopped receiving and sending mail.
I am certain it is because of 11.2, because the same exact e-mail address still works perfectly fine with my 2018 Mac mini, and my iPhone and my iPad Pro.
This is a 2020 Mac mini (M1). It asks for my e-mail password, which I give it, but it comes back saying "unknown verification error". I have verified that it is the correct password. Everything was working fine under 11.1. How should I proceed to fix this?
Mac mini, macOS 10.13
