    dma - Fix security hole
    * dma makes an age-old mistake of not properly checking whether a file
      owned by a user is a symlink or not, a bug which the original mail.local
      also had.
    * Add O_NOFOLLOW to disallow symlinks.
    Thanks-to: BSDNow Episode 152, made me dive dma to check when they talked
    	   about the mail.local bug.
