       RecvDataFormat
              The  data  format  (compression  scheme)  to  write
              received facsimile data when copy quality  checking
              is  enabled on the host.  (When copy quality check-
              ing is not done by the server the received  facsim-
              ile  data is written exactly as it is received from
              the modem.)  The format may  be  one:  ``1-D  MR'',
              ``2-D  MR'',  ``2-D  MMR'',  or  ``adaptive''.   An
              ``adaptive'' format causes the received data to  be
              written  using  the  data  format negotiated by the
              sender and receiver.  Note that while  2-D  MMR  is
              the  most space-efficient data format the resultant
              file may not be  viewable  (certain  commonly  used
              programs do not properly read multi-strip TIFF with
              2-D MMR data).

I think the problem is the Sportster doesn't do copy quality checking.  You
might need to do some post processing in the faxrcvd script
