Actually, that's not going to stop them. If mail gets delivered directly to Exchange, just make sure their address doesn't exist in the system. If you have a mail relay in front of Exchange, then you want to be able to set that to reject those addresses.
The reason being that, over time, rejected addresses get pruned out of spam lists, which means you stop receiving that mail. Blackholing it, as Tony suggest, will work, but that won't get the address off the lists. We're in the process of recovering an old corporate domain which hasn't been actively used in two years (due to a period of time in which we were owned by another company). We've been actively rejecting all but a small white list of addresses for that domain for the last 3 months, and have seen a steady decline of total spam, and a total decline in the number of connections for spam to the old addresses. As I've said before, if you accept spam for delivery on any of your systems, you won't be able to stem its tide. That's one of the reaons I don't think things like Trend's eManager, or most of the other antispam, content inspecting solutions work - they accept the mail before testing it, so its just an expensive, automated delete key. ------------------------------------------------------ Roger D.
