I can't see my mail storage folders on the server

I’ve created several email addresses that I already use on Hestia, but when I go to Filemanager to see where my emails are stored, I can’t find any folder in the main “mail” folder at the root, is this normal? how can I see my stored emails please?

If you access the file manger you will access it as “user” and never as root use ssh and you should be able to access the folder

I do access as a user, but even so I can’t see anything
