Actually the whitelisting, which is a lot easier, probably does more to take the load off spamassassin than the blacklisting. I've whitelisted my common correspondents and the lists I subscribe to:

I'm sure that works very well for you, but because email-addresses are so easily forged, using the SA whitelisting directives:
whitelist_from_rcvd, whitelist_from_spf, or whitelist_from_dkim
would be "safer". Just FYI.
Perfectly true and I do use SA's whitelisting and blacklisting features. But the small set handled this way represents a lot of very personal traffic and is easily managed., just editing a text file. No need to restart SA to get it to re-read or recompile a rule set. Formail and grep forked from procmail might nt be as cheap as if I implemented the whitelist in procmails own RE, but the text file is easier to deal with. Either is cheaper than launching spamassassin. I'm sorry if I gave the impression that this has to be an absolutely either/or situation, Its not. Its not as if I rely solely on whitelisting. Its about taking the load off a very heavily tuned spamassassin. If you happen to know the addresses of any of my relatives to forge their address then you'll find there is additional procmail and thunderbird filtering :-) Suppose a 'false negative' does get though. So? I get a couple of false negatives getting past SA each week. That's why we have 'sa-learn'. The spammers keep coming up with new formats and we have to keep up as well. -- Public confidence in the integrity of the Government is indispensable to faith in democracy; and when we lose faith in the system, we have lost faith in everything we fight and spend for.
