Bah; SpamAssassin is the swiss-army-knife of spam filters. It includes 
a bayesian filter (not to mention things like razor and dcc, which are 
constantly up-to-date), and as such, does not require updating the 
rules. Updating the rules can *help*, but it is not required to 
continue functioning at a reasonably high level.

The real criticism I'd level against SpamAssassin as compared to 
bogofilter is that SpamAssassin's bayesian classifier is relatively 
simple. To my knowledge, it doesn't tokenize word-pairs and phrases, 
but just single words; thus, something that uses more advanced 
bayesian techniques (I presume bogofilter fits this description?) may 
well beat it at that particular game---which is where updating the 
rules can help as a compensating factor. It's not like a virus-scanner 
where an out-of-date database is worthless.
