How do I enable and disable SpamAssassins HTML conversion feature?
By default, SpamAssassin automatically converts spam HTML emails into plain text. This is done to prevent your email client from unknowingly running malicious JavaScripts, or “web-bugs” that may be hidden in the HTML. This plain-text conversion may make some HTML emails unreadable. Therefore, if you are worried about having a legimate HTML email flagged as spam and made unreadable, you should diable this feature. To disable the HTML conversion feature, from the “SpamAssassin” section of your Control Panel, select “Leave HTML emails alone”, and click the “Apply” button immediately below. To re-enable HTML conversion, select the “Remove potentialy dangerous HTML from suspected spam” option and click “Apply”.
