At one time we would simply tag the message with a spam score and allow our users to create a filter. However, if our user was forwarding incoming mail to an off-campus address, the spam would forward before any filters could be applied (if filters were even created).
If you're using a *nix based server for this, there is a solution to this dilemma. Instead of a simple mail alias, if you set the forward to be: joeuser: "| procmail DEST=joeuser () another example edu" and write a global /etc/procmailrc that (a) does the institutional spam quarantining first and (b) picks up the value of $DEST and does the forwarding via formail. I can send specifics of what we use if that will help. - Pat -- Patrick P.
