Block email containing HTML?

MS Outlook 2000 SR-1 (9.0.3821)
in Corporate/Workgroup mode.

Is there any way to prevent an email, which contains HTML from reaching the in box or display it as text only?

Plain Text and Rich Text Format messages are all I need.
I could due without the HTML security problems which might show up.

Searches of the MSKB for disabling HTML did turn up one hit for Outlook 2002 with Service Pack 1. You have to edit the registry to turn on the 'Read as Plain Text' feature. See article Q307594. That says to me that similar solutions are not available for anything prior to Outlook 2002 SP 1. Oh, and this is only for un-signed messages. Anything digitally signed will STILL be rendered as HTML.

This page (http://www.slipstick.com/dev/code/zaphtml.htm) also has a few hacks for stripping HTML out of Outlook messages, but I'm sorry to say that this is far from an elegant solution.

So, if you know how to disable Outlook's inborn desire to render HTML, I'd love to know where that checkbox is located.
