Email Filter Appliance Configuration


In this video, I have demonstrated the Email Filter Appliance (E.F.A) Configuration step by step. EFA stands for Email Filter Appliance, this is a virtual appliance for spam fighting, it is built using open-source tools and combines existing open-source projects into one easy to use and fast to deploy package.

EFA is a community-based product and one of the best spam filters on the market. EFA includes well known anti-spam programs like MailScanner, SpamAssassin, ClamAV, MailWatch, Razor, Pyzor, DCC, SQL grey and Image Cerberus.

In this video, I demonstrate how to configure EFA step by step. EFA can be deployed to scan for both inbound and outbound emails, Here we set it up as an inbound email filter. EFA will receive emails from the internet and after screening for spam and viruses, it will deliver the cleaned email to the Mail Server. EFA introduces a menu-driven configuration program named ‘EFA-Configure’ which groups various configuration settings in one place. The EFA-Configure program allows us to configure EFA on a small scale, for further customization we can edit the configuration files. For DNS caching, EFA employs Unbound DNS Server, which speeds up email processing. I’ve demonstrated the advantage of utilizing DNS Cache on the mail server.

After Filtering, to get the inbound emails to the mailbox server, we used postfix transport maps. I’ll try to show you the details of EFA Configurations in the next tutorials. Deploying EFA for Inbound and Outbound Mail Filtering, configuration, and Customization all will be covered.
