KMail notifications

Is there a way, perhaps with dcop or another applet, to query kmail about new messages and then send a notification/email to a remote user? I have a remote TDE system running kmail and I want to be notified when there are new messages. korn might be close to what I seek but seems to need human interaction, unless I misunderstand. A cron script that looks at file date stamps in the user's mail directory probably would suffice, but a TDE approach would be nice. Affected mails are POP3, so no IMAP approach. Thanks. Darrell
