VStream Antispam adds the following headers to each email that is scanned by the Content Based Antispam or Block List engine, but not blocked:
X-VStream-Spam-Level. Contains an integer between 0 and 100, where 100 indicates the highest likelihood that the email is spam.
X-VStream-Engine. The VStream Antispam engine, (either "Content Based Antispam" or "Block List")
X-Spam-Level. Contains one to five asterisks, where five asterisks indicates the highest likelihood that the email is spam.
YESif the email is deemed to be spam, according to the currently configured thresholds.

If your email client allows defining rules based on message headers, you can create rules specifying that emails with certain headers should be moved to specific folders. For example, you can configure your email client to move all emails with the
X-Spam-Flag: YES header directly to a "Spam Email" folder.
