I'm on GMX (a German freemailer). They offer to put spam into a special folder (which you would not download normally). The first time each day when I download my mail from the in-box (via POP) I also get a report which tells the sender and the subject line of the latest spam suspects. I've configured the retention period for the spam-box for 30 days. So, if I suspect important mail has been rerouted I can check via the web interface. It's straight and simple - even I can understand how it works ;-) Willy
