SUMMARY
When you use Exchange 2000, you can prevent the delivery of messages that were sent by a particular user, domain, or event by an automated junk e-mail script that delivers messages that have a blank address in the From box.



MORE INFORMATION
To prevent messages from being delivered, start Exchange System Manager, expand the Global Settings container, right-click Message Delivery, and then click Properties. Click the Filtering tab, and then enable any of the following options:  Senders: Use this option to manage filtered e-mail addresses. If an e-mail address that is displayed on this list is used to send a message to this Exchange Server computer, the message is not delivered to the recipient.

To prevent a particular e-mail address from sending messages to users in this server, click the Add button, and then type an individual e-mail address. To filter all messages from a particular domain, use the wildcard characters. For example, type *@ .com . Archive filtered messages: Click to select this check box to keep filtered messages in an archive. Old messages are not automatically removed from the archive. Before filtering will work it must be enabled on the Default SMTP Virtual Server. To enable message filtering on an SMTP virtual server, perform the following steps:  Click Start, point to Programs, point to Microsoft Exchange, and then click System Manager. If the Administrative Groups container exists in the left pane, expand it, expand the appropriate administrative group container, expand the Servers container, expand the appropriate server container, and then expand the Protocols container. If the Administrative Groups container does not exist, expand the Servers container in the left pane, expand the appropriate server container, and then expand the Protocols container. To expand a container, double-click the container or click the plus sign (+) to the left of the container. In the left pane, click the SMTP container, right-click the appropriate SMTP virtual server in the right pane, and then click Properties. Click Advanced, click to select the IP address for which you want to enable message filtering, and then click Edit. Click to select the Apply Filter check box, and then click OK on each of the next three dialog boxes.</li></ol>

To disable message filtering on an SMTP virtual server, follow the above steps, but click to clear the Apply Filter check box in step 5 instead of clicking to select it.

Messages are archived to the following directory: \exchsrvr\mailroot\ \filter

NOTE: Archive files can quickly become very large. Be sure to include the removal of old archive files in your maintenance plans.</li> Filter messages with blank sender: Click to select this check box to prevent delivery of messages in which the From box is blank.</li> Accept messages without notifying sender of filtering: Click to select this check box to prevent a non-delivery report (NDR) from being returned to the sender of filtered messages. Use this option if you do not want senders of filtered e-mail messages to know that their messages were not delivered.

NOTE: If you receive large amounts of filtered e-mail, you can use this option to improve network and server performance.</li></ul>
