HTML Features Filter

How to get here

Use HTML Features Filter to select which HTML features to search for in messages, how many of the selected features must appear in order for a message to be identified as spam, and what action to take when a message is identified as spam.

Use: Set the following options to configure HTML features filtering.

• No Filtering. Disables HTML features filtering for the selected mail domain.
• Current Domain (selected by default). Select this option to define HTML features filtering settings specific to the current mail domain.
• Primary Domain (default for non-primary domains; not available for primary domains). Select this option to use the primary mail domain's HTML features filtering instead of creating new settings for the current mail domain.

Select the HTML features to detect:

Nested Table	Invalid Tag	Deceptive URL
Hyperlink	Script Tag	Embedded Comment
Image Tag	Mailto: Hyperlink	Deceptive Text

• Number of options detected for an email to be considered spam. Enter the number of the above selected types of HTML features that must appear in an email message before it is identified as spam.
• Action taken on email determined to be spam. Specify one of the following actions to take on a message that contains selected HTML features:
  • Action:
    • Delete. Immediately deletes the message.
    • Forward to Address. Forwards the message to the email address specified in the text box to the right of this option. By default, messages are sent to the root address and stored in a mailbox called "root-bulk". Example
    • Insert X- Header (default). Inserts an X- Header into the message indicating that it was identified as spam and includes the selected HTML features. See also X-Header Explanations.
    • Move to Mailbox. Moves the message to the user's mailbox specified in the text box to the right of this option. If the mailbox does not exist, it is created. The default mailbox is "bulk".
    • None. No action is taken on the message.
• Prefix Subject With. If selected, the subject of a message that is identified as spam by the HTML filter will be modified to begin with the text entered in the text box.
