I want to purchase an SSL certificate for web mail login.
1. If I buy an SSL certificate for acme.com.au can I create as many sub domains as i want using that Cert for e.g webmail.acme.com.au etc without having to buy another cert?
2. Do I load the (purchased) cert into an internal CA (2003 Server) and issue the sub domain certificates?
3. Could i create my own cert using an internal CA as this is not for e commerce to enable SSL?
4. Any tips for moving forward, I want to learn from your experience.
