You can also add the following to your users' .procmailrc file:

:0:
* ^X-Spam-Status: Yes
mail/Junk\ E-mail

... to achieve the same functionality if they are using something else 
(webmail, for example).

There is one downside (or upside, depending on how you see it)... users 
reading their e-mail using POP3 instead of IMAP will not receive the 
"Junk E-mail"-tagged messages because they will be going to a separate 
(not the Inbox) folder. They would *have* to go to a webmail page or use 
an IMAP client.

The good news is that whatever method you use to send stuff to a 
separate folder, you can then use tools like 
http://www.argon.org/~roderick/mbox-purge.html to delete everything past 
a certain timeframe.

One more thing... If you deliver spam messages to your users, you might 
want to consider the "attachment" feature that delivers e-mails to users 
as attachments. That option prevents several bad things from happening, 
and gives the user a more clear and detailed warning - and you get to 
modify it to include additional information, if you want.
