Yes, after building ${run{}{}} with ls of spoolfile I saw that only -D file is there.
Ok, then I just need to forward "content-type" -header with boundary and MIME-version header to script to check its content of the body-data from disk. It think MIME-boundary should not need quoting.
Should this work?
${extract{boundary}{header_Content-Type:}{$value}}
Because
Content-type: multipart/mixed; boundary="frontier"
