Hi All, Hope someone can help me on this one - our users often get those spam emails purporting to be from the "support team" saying their account has been closed or password changed and these are mostly from some spoofed address (eg admin@....). I am wondering is there a way in exchange to filter out emails from fake addresses that don't exist on our domain, or even just from certain addresses so we could prevent users from getting these emails. We're using exchange 2000. We're already blocking the zip attachments with the AV software. Thanks, Peter peter turner | diocese of washington | IT Services Manager | 202-537-6540 | www.edow.org
