Processing Emails from Thunderbird (.mbox files or eml-files)

Dear Knimer’s,

I am looking for a solution to process Emails from Thunderbird (on Linux). Either directly from the TB-files (read-only) or from the exported-files to either an .mbox- or multiple EML-files with the “ImportExportTools NG” add-on.

I would require to get the whole header information of the emails extracted (including the ‘Received: from’, ‘X-Mozilla-…’ and any other info in the headers.

I haved read so far the recommendations at Extract Text From Email and tried the “Tika Parser” as well as the “mbox Reader”.

The Tika Parser" didn’t return the header info, only the the Author, Date/time, Title , and Text.

The ‘mbox Reader’ returned with an “Execute failed: Malformed input!” error. This might come from that this node expects a mbox-file, while the outputed format seems to be a mboxcl2-file (but I might be wrong).

Does anyone have any sugguestions how to I can get the required data into a table (or document.

Is there a possibility to see the “Tika Parser” Code so that i can eventually expand the extraction fields.

Or how the “mbox Reader” can be brought to operation and deliver the required data

Thanks.

PS: I dont need solutions to retrieve data from any kind of servers.
