For the most part, we illustrate sendmail under BSD Unix and its variants (such as FreeBSD). Where AT&T System V (SysV) differs (such as Sun's Solaris 2.x), we illustrate those differences. Our primary focus throughout this book is on V8.12 sendmail . For completeness, and where necessary, we also discuss V8.11 and earlier (such as BSD's version 5, [3] IDA, early Sun, Ultrix, and NeXT).
