In addition to all technical that has been said in this thread and as I see 
from your other postings your are new to this area although a skilled 
programmer some warning. You have to be aware that there are *many* RBLs 
out there and they all have FPs (false positives) stored in their 
databases. You have to be very careful in which RBLs you trust and in what 
way you trust them (reject or just tag as possible spam). sbl+xbl was a 
good choice for a start and if you want to have very low FPs rates. If you 
look in the archives you will some discussion about that topic.
