Hey,
PDF export is possible with latest version of ProofFinder 4.2.5.
If you want email attachments to be exported as PDF you will need select the attachment as well for export. I will suggest following workflow.
1. From the result set you have selected, you will need to make sure attachment/family is included, for which you can right click and Show All Families.
2. Now you will get a new workbench with item & its families just select them and export to PDF using the recreate directory structure of original data.
This will create a PDF for email and folder of the PDF's of the attachment.
Hope this helps.
I guess now we just need a Näive Bayesian classification module, and we are all ready to go!

It just converted my PST files into PDF format very well with all attachments.
Intella PI is the same kind of licence as Proof Finder, one year, locked to a single PC for $99.
Does pretty much what normal Intella does.
