How does a virtual domain differ from a domain?
To add to what Mark said, technically a "virtual domain" is a domain name that resolves in the domain name system to the same IP address as the primary ("real") domain name for your host. A server host can have many domain names, all pointing to the same IP address, and this is common for web and mail servers these days.
If the protocols supporting the service to the host support it, the particular service agent (mail server, web server, whatever) can determine the name by which it was addressed and do something intelligent with it. This ability is built into the HTTP1.1 standard, and also into the SMTP standard. A list server sits behind a mail server, so technically it _could_ do something with the virtual domain name. It all depends on the way the service agent handles this information.
