An excellent companion to our popular sendmail, Third Edition, this book provides a timely documentation of the improvements in V8.13 in parallel with V8.13's release. The reader will learn that what is new is not merely handy or nice to have, but also critical to getting the best modern behavior from sendmail. This is especially important now that spam is on the rise and because mobile technology requires roving laptops to use encrypted connections. Many of the changes and additions to V8.13 were driven by the ongoing fight against spam. Anyone concerned about this issue will benefit greatly by upgrading to V8.13 sendmail. The additions to the Milter library alone make upgrading worthwhile, but sendmail itself also adds connection control! 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. To understand all that is new, and if you need to set up or manage sendmail, you will appreciate a reference like this.
