spam score checker

Hi

In my project I am going to send newsletters to our clients. Here I
need to validate my newsletter(content). Also I need to show the
content's Spam score. I need to check the spam score for only body
content not header. I have tried with Mail-Spamassassin-3.2.4, the SA
is written in Perl API. The SA will check the both header and body
content like ,

..ie n .IP "$score = $status\fR\->\fIget_head_only_points()" 4
..el .IP "$score = \f(CW$status\fR\->\fIget_head_only_points()\fR" 4
..IX Item "$score = $status->get_head_only_points()"
Return the message's score as computed for auto\-learning, ignoring
all rules except for header-based ones.
..ie n .IP "$score = $status\fR\->\fIget_learned_points()" 4
..el .IP "$score = \f(CW$status\fR\->\fIget_learned_points()\fR" 4
..IX Item "$score = $status->get_learned_points()"
Return the message's score as computed for auto\-learning, ignoring
all rules except for learning-based ones.
..ie n .IP "$score = $status\fR\->\fIget_body_only_points()" 4
..el .IP "$score = \f(CW$status\fR\->\fIget_body_only_points()\fR" 4
..IX Item "$score = $status->get_body_only_points()"

how to enable the get_body_only_points function? Please help me

thanks
