The look up is made against the sending (Connecting) server. A better
option (IMHO) is to use the RBL's in SpamAssassin possibly with some (a)
very conservative list on your MTA. For example, don't reject at MTA
using SpamCop for example. A good list but can provide FPs due to it's
more aggressive nature. I look to all the RBLs to add to the overall
points score in SA where a more balanced view can be taken (And it looks
up all hops the message has taken not just the last one!).
