Email Viewer

This app integrates the fantastic Email to PDF Converter from Nick Russler into Nextcloud to view msg and eml files online.

Server configuration

• Nextcloud 28 (with viewer and files_pdfviewer)
• OpenJDK
• wkhtmltopdf
• Email to PDF Converter

App setup

• Place the app in your apps folder.
• Store a copy of Email to PDF Converter on the server. Nextcloud must have access to it.
• Enable the app (via occ app:enable files_emailviewer).
• Set the path to Email to PDF Converter via occ config:app:set --value /opt/emailconverter-2.6.0-all.jar files_emailviewer binary_path.

Outgoing connections

If the message contains images from outside sources, Email to PDF (actually wkhtmltopdf) will download the image, which means external connections are required.
