Thanks, Magnus, I forgot about fakereject. Actually, the most compelling
usecase for this feature is to fakereject all of your high-scoring spam,
but deliver it not to the quarantine, but instead to your spam corpus
archive. That lets you do post-facto analysis on your spam filtering
performance, and makes it easy to determine how new rules or score
changes would impact that performance.
