Those files are used by SpamAssassin for its auto whitelist and its 
Bayesian classifier.  You shouldn't delete them unless (a) the data has 
been corrupted or (b) you turn these features off in your SpamAssassin config.

The auto whitelist is more of a score averaging system - it adjusts scores 
based on what else that sender has sent you in the past - and if you have 
it running it updates the data whenever SA processes a message.

The bayes database learns from the spam and non-spam you get, based on 
manually teaching it ("This folder is all spam, this one is all non-spam") 
and/or on messages that SA scores very high or very low, if you have 
auto-learning enabled in your SA config.  (The key command here is sa-learn).

In both cases, information is always being added to the database, so you 
can expect the files to keep growing until data starts expiring (see the SA 
docs for more info).
