If you need to serve several domain names that point to a web site hosted on another server, you should set up domain forwarding: see the section "Serving Domain Names for Sites Hosted on Other Servers (Domain Forwarding)" for instructions.
To set up a domain alias:
Domain aliases can comprise letters, digits and hyphens. Each part of the domain alias between dots should not be longer than 63 symbols.
