I'm (slowly) wading through the archives (interesting reading, but *long*), and have reached about this point.  It does seem that the majority of the testing was done on certain collections of spam (along with lots of different ham).  I wonder whether things got tuned a little too closely to that, and now that the spam is a little different, some options might need to be relooked at (rather than just retraining).

Once I'm done with the archives (and then the options stuff), I'll try and set up a testing system so that I can work on that.  I'm personally most interested in the effects of aging, the ham:spam ratio (with the current code), and how long spambayes takes to become effective, so I'll concentrate on those.
