The first step is to add a DNS A record for email.test.com. This is done outside of Web Server, usually by editing a BIND zone file.

Once you have an A record for email.test.com, you can create a new virtual server using the Web Server administration console or CLI. If you choose to use the admin console, click New Virtual Server on the Common Tasks tab. Make sure to specify email.test.com as the host.
