I want DTPO to import emails as PDF files and their attachments as they are, unless the attachments are emails too. In this case the attached emails should beeing importet as PDF files as well. Is DTPO3 doing it?
No. Emails aren’t imported as PDFs and attachments in emails aren’t separated and converted to PDF. Emails are imported in a similar fashion as DEVONthink 2.
It may be possible to script something but there’s nothing specifically built for this purpose.
