[exim] Web-application for spam quarantine?

Hi all,

I'm considering replacing a proprietary antispam-appliance with a rather
normal/ordinary exim+spamassassin+kaspersky-setup. However, currently
the appliance stores each spam and sends periodic reports to the
recipients containing a list of messages kept by the appliance. Using a
webinterface the users identify false positives which are then delivered
to their inboxes.

Does anybody know of any software that offers such a quarantine and
integrates well with exim?

I suggested to have messages marked as spam to a special folder, but a)
it is feared that the users won't adapt to such a change and b) the
storate-server is MS-Exchange and nobody knows how to globally define a
filter to deliver marked messages to special folders.

Yes, I know, I'm not going to recieve the award for the "most on-topic
message ever", so I hope you just focus on the "integrates well with
exim" line. ;-)
