Thanks much for your time & wisdom.  This is a disciplined way to use 
the RBLs, as opposed to blindly using all that show up in the 
SpamAssassin rules.  I'll definitely do some exploring & trying out the 
various services to see which we want to use.  In the meantime, 
shortening those delay limits will definitely help us protect our 
performance if any of them has problems.

Cheers,
