He tries to receive a fax, hence don't even touches the fax-file.

efax.rc is parsed by the helper script /usr/bin/fax..

Well, didn't work either, he tries to receive a fax...

Seems to be OK.

Summary:
The only difference between the new and the old dvi2fax script seems
to be, that the device name in the gs call was changed from faxg3 to
dfaxhigh. It is IMHO a bug of efax, that files of the form

drachi:[~/efax] #file truc-new.fax
truc-new.fax: group 3 fax data, fine resolution (204x196 DPI)

are not understood by it, meanwhile

drachi:[~/efax] #file truc-old.fax
truc-old.fax: raw G3 data

are. So I'm swapping over that bug to efax. Filippo, if you think
this is not your fault, please reassign that bug to ghostscript.
Seb, if you want to send faxes using efax you can use the helper
Skript /usr/bin/fax. Just feed your created Postscript file to it and
leave the conversion to the efax-suite. This is confirmed to work.

Thanks to all contributors,
