Beware Mail Data Loss in Catalina

[ace (Adam Engst)]

Still not safe in 10.15.2…

Apple Pushes Out iOS 13.3, iPadOS 13.3, iOS 13.3 for HomePod, macOS 10.15.2 Catalina, watchOS 6.1.1, and tvOS 13.3

Importing/rebuilding and moving messages between mailboxes can both still lose e-mails in macOS 10.15.2.
