A number of updates based on the SpamBayes techniques made it into
Thunderbird starting with the 0.6 release.  They are using our chi-combining
formulas, are now splitting (mostly) on whitespace only, and are counting
each token only once per message.  They have also incorporated some
tokenizer changes, but it doesn't appear to be an exact match for the tokens
we generate.  They also do not support the "unsure" category.

Anyone who is interested in more discussion of these changes can take a look
at these Mozilla trackers:
