No -- unless you ultimately trust the RBL to produce a *negligible* amount of FPs. Every single RBL does have FPs to a highly variable degree. Instead ob outright blocking on a hit, it is a good idea to assign a score for the hit only, and see what the result is after all tests have been performed... Exactly the SA approach. A single (or even a few) rules and RBLs can misfire, without affecting the overall deliverability of a particular mail. > > Also look at setting up Bayes and train it well.

As mentioned a few times already -- do train Bayes instead. That's a mis-fire of Bayes, and needs to be corrected. guenther -- 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; }}}
