Question:

How do I add a disclaimer or stamp containing images to outgoing e-mail?

Procedure:

The HTML <img> tag can be used to include a web link to an image within a message stamp. 

The instructions below apply to SEG 8.X and below. Similar abilities exist in MailMarshal (SEG) 10 (see MailMarshal (SEG) 10 Help for detailed instructions on stamp creation in MailMarshal (SEG) 10).

  1. Create a Content Analysis (Standard) Rule similar to the following rule description:
    When a message arrives
    Where message is outgoing
    Stamp message with message stamp
    And pass message to the next rule for processing.
  2. To create the stamp, click the message stamp link in the rule. The Select Message Stamp window will open.
  3. Click New Stamp and give the stamp a name (for example, "Footer Image").
  4. Click the HTML tab.
  5. In the editing pane (blank space), right-click and select Edit Raw HTML...
  6. Between the <BODY> and </BODY> tags, insert the following to include the URL for your image:
    <IMG SRC="http://www.YOUR_URL_GOES_HERE.com/IMAGE_DIRECTORY/IMAGE_NAME.jpg">
  7. Click OK on the HTML Raw window.
  8. Click OK on the Edit Message Stamp window.
  9. If a warning pops up, click YES.
  10. Make sure the new stamp is enabled in the Select Message Stamp window and click OK.
  11. Give the rule a name, enable it, and click Finish.

    The completed rule text will appear similar to the following:

    When a message arrives
    Where message is outgoing
    Stamp message with 'Footer Image'
    And pass message to the next rule for processing.

  12. Commit configuration.

This rule will stamp all outgoing HTML e-mail with an external link to an image or logo. 

Notes:

  • MailMarshal does not currently support embedded images, only external HTML links.
  • At the recipient end, the mail client must have web access (and not block images) for the image to appear correctly in the stamp.
