How can a plugin report a dynamic score to SpamAssassin 3.1.7?

[Alban Deniz]

Hello,

I've written a Sniffer plugin (SNF4SA) for SpamAssassin, and my plugin doesn't 
report dynamic scores for SpamAssassin 3.1.7.  The dynamic score reporting 
works correctly for SpamAssassin 3.2.5.

I would like to know if there's a way to report dynamic scores in SpamAssassin 
3.1.7.  I haven't been able to find info for this on the FAQ or on the 
FrontPage.

Here's a description of my problem:

The SNF4SA plugin reports a dynamic score as follows:

# Check the message with SNFServer.
sub snf4sa_sacheck {

 my ($self, $permsgstatus, $fulltext) = @_;

 # $deltaScore is the score to add.

 $permsgstatus->got_hit("SNF4SA", "", score => $deltaScore);
 for my $set (0..3) {
     $permsgstatus->{conf}->{scoreset}->[$set]->{"SNF4SA"} =
         sprintf("%0.3f", $deltaScore);
 }

}

This works with SpamAssassin 3.2.5 on Ubuntu 9.04.  It doesn't work with 
SpamAssassin 3.1.7 on Fedora Core 2 (although it does after upgrading to 
SpamAssassin 3.2.5 on Fedora Core 2).  I understand that the got_hit() 
function does not accept dynamic scores before SpamAssassin 3.2.0, which 
explains this.

My question is:  Is there a way to report dynamic scores with SpamAssassin 
3.1.7?  I'd appreciate any help.

Thanks,
Alban
