I am pretty sure the current buffer contains the message while
splitting, you don't need to change buffers.  Look at the spam-split
function in spam.el, it does body-based analysis for statistical spam
filters.  Remember you have to set the nnimap-split-download-body
variable if you want to see the whole body with nnimap splitting.
