What is this?

This tool is an External Agent for ORF 2.1 and newer versions that improves ORF by PDF spam detection capabilities.

What is PDF spam?

PDF spam is a subtype of spam which has the payload in attached PDF documents. This agent was developed specifically against a 2007 PDF spam outbreak. Since then, PDF spam virtually disappeared from the Internet, so this agent is listed for demonstration purposes only — if you are interested in developing your own External Agent for ORF, the source code (C#, .NET 2.0) was made available for you to study under GNU Lesser General Public License (LGPL).
