Auto-delete Old Spam

I'm now sending all spam on my domains to a spambox (one for each domain).<br /><br />People are *supposed* to check and delete email from this box, but no one does, really. Since no one is deleting mail in these boxes, it is piling up -- 8000 messages in one such box. <br /><br />Can anyone recommend a script or utility that can automatically (cron job) delete spam that is older than n days?<br /><br />I've seen archivemail at sourceforge, but haven't read much on it. If no one has suggestions, this may be my next experiment.<br /><br />Thanks,<br /><br />Todd<!--content-->
