The next step is to configure the SMTP application filter. Click the Extensions node, then double-click the Application filters folder in the right pane. Now, double-click or right-click the SMTP Filter and select Properties. In this configuration area, you can enable filtering on attachments by filename, extension, or size. To add filtering keywords, select the Keywords tab, then click Add and type in a word you want to filter on. You can filter on words in the Message header, Message body, or Message header and body. Notice that you must enter the words or phrases one at a time. Unlike products from other vendors, the SMTP Filter doesn't have an import function to bring in an established list of offensive phrases from a file or vendor Web site. Therefore, you must be creative and aware of every possible offensive or naughty phrase! (In "Managing Your Email Content, Part 1," I discuss content-management software that provides an established list of offensive phrases.) Finally, from the drop-down list, select the action (Delete, Hold, or Forward) you want the filter to perform on the messages. You must manually enter the email address to which you want the messages forwarded; the filter doesn't resolve names from the Global Address List (GAL). Also notice that you can use an arrow to move the keywords up or down. Keyword order is crucial because the first match triggers the defined action. If you delete a message because it contains a certain word, the fact that a later keyword match would have forwarded the message to you is irrelevant. You won't receive the message. . . .
