IMAP namespace not possible
In some clients you can set an IMAP namespace (e.g. mail/) that would be appended to the user's $HOME directory. In this way I don't have all my email folders directly in my home directory on the server.
the structure in $HOME would be something like
Desktop
mail <- this is where VO should work with my mail
- Folder1
- Folder2
- Folder3
- SubFolder31
- SubFolder32
- SubFolder33
Tempstuff
Is this possible in VO?
