    ...that does not solve the problem...the info-file for this destination
    clearly reports the 2D capability of the remote fax, but hylafax still
    selects 1D encoding! :(
    
    hints?

Submit a job and check the spool/sendq/qXXXX file for the value of
"desireddf" (should be >0 for 2-D MR) and if you send a PostScript
file (or a text file converted by textfmt(1) to PostScript) make also
sure that ps2fax(1M) use the tiffg32d-driver converting the file to
TIFF/F, e.g. do:

$ gs -h | grep tiffg32d
$ gs -h | grep tiffg3
    x11 tiffg3 pbm pbmraw pgm pgmraw ppm ppmraw

(my gostscript doesn't support tiffg32d).
