If it had ever been reliable, I would.

See this [2[ stack overflow post. Thank you for the info. Not sure I want to dive back into perl after a pretty happy nearly 20 years of avoidance, but maybe. I certainly do not want to strip all HTML from all user mail. Really I just want to remove the HTML from the few lists that for reasons I cannot understand, allow HTML to be posted to them.
