I used to use a filter before the Mailman wrapper which ran rblcheck
against the headers and added a custom X-Header if a match was
found.  I didn't do it in the MTA at the time as I only wanted it
for the one list.

I no longer have that script, but it was based of the following
procmail recipe:

  TCPREMOTEIP=`formail -xReceived|/bin/sed -ne '/\[.*\]/{ s/[^[]*.\([^]]*\)[^$]*/\1/; P;}'`
  RBL=`if [ -n "$TCPREMOTEIP" ]; then rblcheck ${TCPREMOTEIP} | /bin/fgrep -v "not RBL filtered"; fi`

  :0 fhw
  * ? [ -n "$RBL" ]
  | formail -A"X-Spam-Flags: $RBL"

rblcheck can be found here:

The pressure to survive and rhetoric may make strange bedfellows
