The latest available version of sendmail <http://www.sendmail.com/sm/open_source/> is " Sendmail 8.15.1"; however, I think you would be better served by installing the latest version of Postfix, which I believe is "Postfix 2.11 Patchlevel 3". I believe, perhaps incorrectly, that the next stable version of Postfix will be released shortly, so perhaps you might want to wait for a short time. Just my 2ยข. -- Jerry
