Actually quite the opposite. :) Rather than increasing a score, it is used to 'rescue' legitimate bounce messages. See the docs [1]. Basically, it serves two purposes: (a) Setting this option enables the VBounce plugin, and (b) it prevents legit bounces from being marked with the ANY_BOUNCE_MESSAGE and friends rules. Of course, we can't stop you from assigning a custom, absurdly high score to ANY_BOUNCE_MESSAGE to abuse the existing score based filtering. However, the purpose of this plugin and the low default score is to not weigh in into classifying spam, but to provide a nice handler (see my previous post) to identify bounces and treat them specially. guenther [1] http://spamassassin.apache.org/full/3.2.x/doc/Mail_SpamAssassin_Plugin_VBounce.html -- char *t="[EMAIL PROTECTED]"; main(){ char h,m=h=*t++,*x=t+2*h,c,i,l=*x,s=0; for (i=0;i<l;i++){ i%8? c<<=1: (c=*++x); c&128 && (s+=h); if (!(h>>=1)||!t[s+h]){ putchar(t[s]);h=m;s=0; }}}
