ESVA is a pre-built and semi-configured email scanning (security) Virtual Appliance (ESVA) that will run on VMware Workstation, Server, Player or ESX Server. The idea is for the appliance to be set & forget with an easy to use web-based interface.
As you may know, the ESVA (Email Security Virtual Appliance) project has died. I am reaching out to inform you that the E.F.A. Project is the successor to ESVA, and that Version 184.108.40.206 is now released. Google "E.F.A. Project" for more information Please be aware that ESVA is vulnerable to CGI injection attacks via learn-msg.cgi and release-msg.cgi that are open to the Internet.
Yes. I initially used this package to redirect mail off of port 25, but found it's spam filtering an added bonus. As a VMWare virtual appliance it's been up for over 3 years with minimal periodic maintenance.
