When you add an image to your local client approved or blocked image lists, the image is scanned and a signature is constructed for the image. When adding an image to your client approved images list, you can also request that the image is added to the global approved image list if it is also relevant to the Image Control community. This option supports other organizations, and similarly, if this option is selected, images they contribute support you, resulting in fewer emails that are triggered incorrectly. Images that are specific to your organization should not be submitted to the global list.
The cloud security services manually review every image that is submitted to the global list to ensure that an image is not added incorrectly.
You cannot submit images to be entered on the global blocked image list, for legal reasons. The portal does not provide the functionality to do this. It is an offense to distribute certain indecent images and to save them on to a computer.
To add an image to your client approved or blocked image lists
Click Services > Email Services > Image Control.
In the Approved images or Blocked images tab, as appropriate, click Add image.
The Add new image window is displayed.
Click Browse to locate the image file to add.
Enter a description of the image.
The description must not exceed 255 characters. We recommend that you use meaningful descriptions and avoid unacceptable language. When a suspect email is detected, the image description may be included in the notification email sent to the administrator and in statistics and reports.
If the offending image is appropriate to be added to the global approved image list (that is, is not specific to your organization), check Email image to Messagelabs for analysis and inclusion within the global image community.
The image is emailed to the cloud security services for analysis and is added to the global approved list if it is appropriate.
This option is only available for approved images.
The image is automatically assigned a unique ID, which is displayed in your list of client approved or blocked image lists, as appropriate.
If the image is already in your list, an error message is displayed to ensure that there is no duplication within your lists.
