AFAIK, that option doesn't have an install time option.

If you can at all enable rbl checking in the MTA and disable that option
 it would be *much* better then having SA do it.  It's a lot cheaper for
the MTA to just bounce the crap because of being linked directly to name
lookup libs and all than if it has to accept the mail and then feed it
off to several somewhat Memory, CPU, and I/O hungry processes.

Indeed, I observe that a majority of the spam at my site is being
bounced through the use of several rbl lists.  I'm not even blocking
dynamic or dialup IP ranges yet, but I just may soon given the quantity
of crap emminating from attbi.
