in thread Routing SPAM emails to a junk folder

Just a wild thought: give every user two e-mail addresses: the real one is "user@my.email.server" and the one for the spam is "spam.user@my.email.server".

If you make the spam-box only available through webmail, your users do not have to download through all the spam-messages and you can easily delete these message after a reasonable expiry-period.
