WorkgroupMail can produce formatted signatures that are attached to outgoing emails by using a
rule in the Content Filtering plug-in in conjunction with an HTML file containing the formatted signature.
Create an HTML file containing your signature. If you wish to include bitmap images such as logos, then the image must be completely contained in the file
Add a new rule that would check messages before sending, with no particular conditions (for all
mail) or messages sent to external recipients (for external mail only), and to add a disclaimer.
Edit the disclaimer and specify HTML format. Copy the HTML code required (from the signature file)
and paste it into the disclaimer text box.
