I'm guessing the data dir Bob mentioned is a queue mail goes in while 
it's being filtered.  Is that right?

If you're going to add to the spam processing, I'd add greylisting first 
(in fact, if I ever add spam filtering to my mail server greylisting 
will come before spam assassin).  Here's some info about spam in general:

and Sean Reifschneider has some interesting bits at

There's also Barb Dijker's presentation on greylisting at:

(there was a guy who supposedly had a "good" list of blacklisting 
services--maybe Barb or Sean would contribute some config advice to CLUE).

Seems to me the downside is hands on management of the blacklists. 
Maybe it's easier than I think.  But I saw an add for a 250GB drive for 
$100, too.
