PerfectMail™ can mark spam messages so that your desktop mail client (e.g. Outlook) can filter your e-mail based on PerfectMail's assessment. This information is stored in the X-Spam-Flag and X-Spam-Level e-mail headers. These headers can be used to filter spam with your e-mail client.

To filter e-mail flagged as spam you need to create Filter Rules. Filter rules can automatically file messages in your "Spam" or "Junk" folder. For sites that are particularly concerned about loosing e-mail, or even for specific users, you can have PerfectMail not reject any e-mail and use these filtering rules to filter messages on your local e-mail client.

The steps for creating filter rules are specific to your e-mail client. We have instructions for creating filter rules for several popular e-mail clients. The steps for other e-mail clients are likely very similar to those presented here.
