About eFa Project

eFa stands for Email Filter Appliance The idea about eFa is to create a (virtual) appliance for spam fighting using open-source tools. We try to combine existing open-source projects into one easy to use and fast to deploy package.

eFa is a community based product, with each other we try to create the best possible spam filter product out there based on existing open-source software.

In January 2014 the first release of eFa 3.x was released based on CentOS for the Operating system, Postfix for the Mail Transport Agent and MailWatch as the web interface.
