I don't believe theres currently any way of doing this with MailScanner,
however if you use SpamAssassin to do the RBL checks you can do it.

I _think_ its done by adding something like the following to
spam.assassin.prefs.conf

header RCVD_IN_TCATS rbleval:check_rbl('relay',
'accept.the-carrot-and-the-stick.com.')

describe RCVD_IN_TCATS Listed in TCATS see
http://www.the-carrot-and-the-stick.com/

tflags RCVD_IN_TCATS net nice

score RCVD_IN_TCATS -10

[NOTE: the first two pairs of lines are single lines which my mail
client has wrapped] You can set the score to what you like (but it
should be negative).

I basically nicked the above from the way spamassassin handles the
bondedsender.org whitelist.
