+If your host is known by several different names, you need to augment
+the $=w class. This is a list of names by which you are known, and
+anything sent to an address using a host name in this list will be
+treated as local mail. You can do this in two ways: either create
+the file /etc/sendmail.cw containing a list of your aliases (one per
+line), and use ``FEATURE(use_cw_file)'' in the .mc file, or add the
+line:
+
+ Cw alias.host.name
+
+at the end of that file. See the ``vangogh.mc'' file for an example.
+Be sure you use the fully-qualified name of the host, rather than a
+short name.
