If you've got fetchmail configured to retrieve messages from a remote 
MTA and deliver to a local MTA, say your local Sendmail instance, then 
put the RBL-matching stuff in your Sendmail configuration.  The mail 
will still be fetched but will be discarded by your local MTA before 
dumping it in you local mailbox.

In principle, it would be better to have the system you are fetching the 
mail from do the RBL operations, but if you don't have control over it 
then you really don't get much choice.  I'm using this setup myself and 
it works, but it offends my aesthetic sense.  OTOH, I'm easily offended!

Your mileage may vary.
