Generate an e-mail on page-not-found (404) errors [support thread]

[lat9]

Got it! If the email address to which the 404 emails are to be sent was used as a test-customer account email and that customer account uses HTML email settings, the email described by torvista will be sent. I've submitted v1.2.1 to the plugins area to correct the problem and describe how the HTML/TEXT emails will be sent.
