SAFER has now joined Project LACE, http://www.project-lace.org, and as such has a website there. Check out SAFER's new website, http://www.project-lace.org/software/safer/ for the latest news and information on the progress of SAFER.
The first source release of SAFER(Simple Agent For Email Routing) has been released. The code is still Alpha, which means bugs, but it functions enough to check it out.
SAFER is a program to allow you to split your users on a domain name among several email servers without having to edit DNS. SAFER will support multiple domains, and is very easy to configure. Since it is currently Alpha code, bug reports are greatly accepted throught he project summary page. http://www.sourceforge.net/projects/safer/
