Actually that isn't too hard to do.  With Honey-dan-ber, you can
set up the Permissions file to run your own "rmail" program.  e.g.:

  MACHINE=OTHER COMMANDS=/usr/lib/uucp/rmail

The /usr/lib/uucp/rmail script could be something like:

  # Only allow mail from certain sites to be passed along to "attmail".
  # This is to prevent "freeloading" from other sites.
  #
  case "$1" in
    attmail*|*@attmail)
	  case "$UU_MACHINE" in
	    akgua|akgub|akguc) ;;    #  Allow these sites
	    *)    if [ `echo "$UU_MACHINE" | egrep -c "$ALLOW"` -eq 0 ] ;
		    then  echo '\nYour site not authorized to send to ATTMAIL' >&2
			  exit 1
		  fi
		  ;;
	  esac
	  ;;
  esac
  
  /bin/rmail $1
