Spot Documents has announced that its tool for archiving Apple Mail will be offered for free for a limited time. Email Archiver saves all of a user's e-mails as PDFs, and automatically organizes these files into a hierarchical folder structure. Each PDF includes all relevant e-mail header information, while attachments are stored in a folder beside their corresponding messages. The application generally sells for $10 through the Mac App Store, however, will remain a free download for the next week.
