This is an old revision of the document!
Eudora allows filtering based on any mail header, which is great - everything can be done completely in the background, without changing the subject lin!
So the easiest method of setting up filters for POPFile's classification is to turn on the X-Text-Classification insertion on POPFile's Bucket page.
