once a message has been [correctly] trained there is no need to keep it
around. however, spambayes' accuracy is dependent upon having a
'sufficient' sample from which to make its decisions. therefore, most
users retain a fair amount of spam in the event that they may wish to
rebuild the corpus from scratch.
of course, this begs the question: 'how much is enough?' that is where
the 'art' of spambayes meets the science :) personally, i keep a couple
thousand spam--two month's worth--as well as a similar number of ham.
that is not to say that you won't have excellent results with a tenth
(or less) of that number; since everyone's e-mail profile is different,
the requirements for training are as well.
