To enable, edit the masquerade_domains parameter in the main.cf file and specify one or more domain names separated by whitespace or commas. The list is processed left to right, and processing stops at the first match. Thus, masquerade_domains = foo.example.com example.com strips any.thing.foo.example.com to foo.example.com, but strips any.thing.else.example.com to example.com.
