I don't have an ALT specified in the mail location of the shared namespace. Also when I add there ALT= I keep getting these checks. Also creating empty file there creates this error.

Error: t_readlink(/xxxxxxxx/mdbox/dbox-alt-root) failed: readlink()

I don't really like the idea of creating a symlink to the same storage.

I am getting this error. This file does not exist.

Error: t_readlink(/xxxxxx/dbox-alt-root) failed: readlink() failed: Permission denied
