Mac Finder does not show entries like
/Users/~/Library/Mail/V3/POP-eharrold@mail.example.com
as described in
Mail (El Capitan): Import or export mailboxes
https://support.apple.com/kb/PH22318
Instead, it shows something like
/Users/~/Library/Mail/V3/123ABCDE-456E-6678A-C345-D436B6EEEE6A
The consequence is that such format is not recognized by Apple Mail "File - Import Mailboxes", which makes a mess and reports missing messages when trying to import mailboxes and mails from there.
How to fix it? Thanks.
