Requirements for Name Services

This section describes the requirements that sendmail imposes on name services.

A host table or map in a name service must be set up to support three types of gethostbyname() queries.

Two additional rules about the host name service need to be followed to establish efficient sendmail services within a name service.

For more information about the gethostbyname() function, refer to the gethostbyname(3NSL) man page.
