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.
max at sade:~/etc% ls -l
total 190424
-rw-r--r-- 1 max users 190592594 Aug 20 13:13 Mailbox.backup
-rw-r--r-- 1 max users 4201081 Aug 20 13:13 unspamlog
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
filter to provide input to another nacent spam filter, at this point of
questionable value.
As a benchmark, Graham's indication was that each of his corpora had
about 4000 messages in it.
