I have setup Sender filtering under Global settings and have confirmed that we are blocking from entries made in the Senders. I have checked the Archive filtered messages option and currently do not have the "Filter messages with blank sender" or "Drop connection if address matches filter" checked, but do plan on utilizing this in the future. I read the following in MS Article ID : 821881: "If you want the filtered messages to be moved to the Exchsrvr\Mailroot\Server_Name\Filter folder (where Server_Name is the SMTP virtual server that the message is filtered for), click to select the Archive filtered messages check box on the Sender Filtering tab." The Filter folder is not being created even though we are successfully able to block messages. Any idea on where they might be created? Thanks for any assistance, Dan
