I do precisely that, use procmail to filter all mailing list mail straight into my mbox,
and then what's left is piped through spamc which flags the spam. KMail then
simply reads the mbox and does normal filtering into different folders. All the heavy
processing is done in the background by daemons and the KMail UI remains responsive.
