[exim] spam assassin

Hi,

I am trying to incorporate spam assassin into exim 4.50.

It is all setup and working execpt that I dont know the varible to send the
acl_check_data spam option, so that spamassassin will check the userpref
from my sql database of the user supplied.

Example:
warn message = X-spam-score: $spam_score
        spam = test:true

Log From SpamAssassin:

logmsg: connection from localhost [127.0.0.1] at port 32846
debug: Conf::SQL: executing SQL: select preference, value from userpref
where username = 'test' or username = '@GLOBAL' order by username asc
debug: retrieving prefs for from SQL server
