However, I may be taking too-conservative a stance here. It's possible that, while HTML comments can appear in ham, *long* HTML comments won't, and the fact that we're looking for long blocks of comment text is enough safety.
That's why feeling. You'll notice my rule is dumb: it's simply looking for a bunch of stuff in a comment. My main feeling is that if anyone is sending HTML email with LOTS of stuff commented out, that email is almost certainly spam. Ham HTML email would probably be done with more care.
Yes, there's the chance for FPs, if some company decides to send a legitimate (ham, opt-in, etc.) HTML email from a badly-written template where the designer was a lazy bum and left giant commented-out sections... but would you really want such an email anyway? ;-)
