Fortunately, I do have a possible solution: I keep all mail that comes
in through my new rule-based filter, and the filter logs whether or not
each mail was considered spam and why.

This does mean writing something to process through that data and
separate it into the two corpora, but it isn't too unreasonable. But it
does make it a little strange in that I'd be using one (successful) spam

As a benchmark, Graham's indication was that each of his corpora had
about 4000 messages in it.
