Mail has stopped displaying HTML messages. Why?

I am running 10.6.8

For some reason I can not fathom, Mail has stopped displaying the content of emails with HTML formatting. All I get is:

To view the message, please use an HTML compatible email viewer!


It used to work fine, so what has happened? I've checked the Preferences to make sure HTML is enabled.

Thanks.
