TCP wrapper filter server-host specification

You can further identify the specific service being requested in a TCP wrapper filter by including server host name or address information in the  service-specification entry. In that case the entry has the form service@host-specification.

You might want to use this feature when your Messaging Server host machine is set up for multiple Internet addresses with different Internet host names. If you are a service provider, you can use this facility to host multiple domains, with different access-control rules, on a single server instance.
