Which software can I use if I want to print a file with mime-type message/* or multipart/* (eg: message/rfc822, multipart/mixed etc, eml/hta files and such) to a physical printer (laser printer / inkjet printer)?
Or software that can read a message/* file or a multipart/* file, render it and convert it to a PDF file. (which I can print after with lpr [path to PDF file])
Its important that it is headless or have some headless command option, since it will be run from a web upload script and thus have no X terminal attached.
