We are running Exchange 2003 server with Microsoft Office 2007 clients. We have some web applications that send reminder email messages automatically to users and now the messages are showing up in users junk mail. This is a recent development, apparently having to do with the Outlook junkmail filters being updated recently. We know we can ask the user to add the sender to their safe list, but because we have over 800 users, we want to fix it on the server side. Any ideas?
