For a simple dot release (8.12 to 8.13), V8.13 sendmail has added more features, options, and fundamental changes than any other single dot release has included. O'Reilly's new "sendmail 8.13 Companion" provides a timely way to document the improvements in V8.13 in parallel with its release. If you need to set up or manage sendmail, you'll want this book close at hand.
Not surprisingly, many of the changes and additions to V8.13 have been driven by the ongoing fight against spam. Anyone concerned about spam--and who isn't?--will benefit greatly by upgrading to V8.13 sendmail. Among its many enhancements, V8.13 includes new routines that support the SPF sending site authentication standard (in the Milter library), simultaneous connection control, high connection rate control, and finer tuning of SASL parameters. The additions to the Milter library, alone, make upgrading worthwhile, but sendmail's connection control makes it a no-brainer. The key to understanding them is the sendmail 8.13 Companion. The book is divided into twenty-five chapters that parallel the chapters in the third edition of O'Reilly's "sendmail" book. For instance, if you're interested in Options configuration (Chapter 24 in "sendmail"), you'll turn to Chapter 24 in your companion volume to find out what's new in V8.13.
