IMSVA can take action on a message based on its content and where the content appears. See Configuring an Expression for more information on how to specify the content to filter.

Procedure

  1. Go to Policy → Policy List.
    The Policy screen appears.
  2. Create or modify an "Other" (not an Antivirus) policy.
  3. Under Content, on the Step 2: Select Scanning Conditions screen, select the check boxes next to the parts of a message to which you want the content conditions to apply.
  4. Click the link that specifies the part of the message to which you want to configure content conditions. The Keyword Expressions screen appears with two columns:
    • Available: Expressions available for use, but not currently in use.
    • Selected: Expressions currently in use.
  5. If you are configuring expressions for the header, select the check boxes next to the header items where the expression will apply.
  6. Click Add.
    The screen for managing keyword expressions appears.
  7. Configure the expressions.
  8. In the Available list, click the expression list you want to enable.
  9. Click >>.
    The expressions appear in the Selected list.
    To keep an expression list available but temporarily prevent IMSVA from using it, click the expression in the selected list, and then click <<.
  10. Click Save to continue to the scanning conditions selection screen.
