PerfectMail™ can mark spam messages so that your desktop mail client (e.g. Outlook) can filter your e-mail based on PerfectMail's assessment. The information is placed in a special header that you can not see, but which most mail clients use to filter the spam from your e-mail. Specifically, PerfectMail uses two e-mail headers:

• X-Spam-Flag: YES
• X-Spam-Level: *****

To use Distributed Filtering you must enable specific mail headers in PerfectMail. Using your web browser, log into the PerfectMail administrative interface and go to the Filter Settings page on the Actions tab (Filtering > Filter Settings :: Actions tab). Enable distributed filtering by checking/unchecking the following options:

• Reject spam: Uncheck (optional)
• Spam flag header: Check
• Spam level header: Check

Unchecking the Reject spam option is optional. With this option unchecked all spam will flow to all e-mail recipients. Another option is to leave this option checked but to disable filtering for specific users in the Domain Configuration (Domain Admin > Domains). On the Domain Configuration page click on a domain name, then click the Edit Addresses button at the bottom right of the screen. You can then disable filtering for specified users using the Address Maintenance screen.

With these settings each message will contain the e-mail headers, mentioned above, which you can use for filtering using your mail client.
