[ingo] vfs driver does not create path

[kc]

By default the vfs (ftp) driver will not create path if not exist. Is it 
normal?

All user home directory (where sieve script stored) are not exist in my 
virtual host environment.

I have make change to vfs.php in info/lib/driver.

$this->_params['filename'], $script);
