Thank you both for your very helpful replies.Now i have tested a so called valid subCA. In my root CA and subCA configuration files(seperate configuration files) i have basic constraints set to "CA:True" exactly the same as the root certificate. But when i loaded my subCA which was signed by my root CA it gave a certificate chain error. A valid subCA signed by a valid root CA cannot be trusted as far as i can see. Or maybe i misunderstood?.

That's not actually what I meant. I meant that a valid subCA signed by a
trusted root CA is itself trusted.
There is a mechanism to restrict trust to explicit chains in S/MIME but not
currently in SSL.
