A. The client.cf File
In Part I of this book a configuration file that always forwards to the hub was partly developed. This appendix presents it in annotated and cross-referenced form, but please use this file only to learn about sendmail . If you really need a client file that always forwards to a hub, use the nullclient feature described in Chapter 16, The null.mc File and m4 .
