You don't have to use DSPAM's quarantine interface. We use Exchange's
"Junk E-mail" folder which is built-in: X-DSPAM-Result: Spam will move
a message to this folder (and all X-DSPAM* headers are removed before
they hit the DSPAM servers so this can't be spoofed). The "Junk E-mail"
folder's contents are automatically expired after 30 days. This
requires Exchange event sinks, BTW. Users need to forward mistakes
to training addresses.

That might work for a smaller site, but it doesn't scale well and it
places the administrative burden on you.
