I just finished a new project, an EML to PDF Converting tool which i released for free under the Apache V2 License to github. This tool allows you to convert your E-Mails in the EML format to PDF’s, which is necessary for archivability. Since E-Mails reference external resources such as images they tend to be an impermanent medium. To deal with this they can be converted to a format which is permanent such as PDF.
You can download it for free or check out the source code at github!
