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 (virtual) appliance.

eFa is a community based product, we try to create the best possible spam filter product out there based on existing open-source software. See the about page to find out which existing project we use to combine, tune and support to create one great appliance.

Community Support. Real People.

Support for eFa is provided by the eFa community, if you use eFa we would like you to join the community and contribute to the project. Everyone is able to help out it doesn’t matter if you help users on the eFa forums, help out with the documentation or support users on the eFa IRC channel #efa-project on irc.libera.chat, all support is thankfully accepted.

If you want to do more you might even help out with some of the server costs or support with some of your spare hardware resources you have by donating. Participating in the community is our preferred way of contributing to make eFa the greatest product around.
