Perhaps I've used the wrong terminology. I mean that convert_html_to_plaintext is set to Yes.

I've attached a screenshot of the content filtering page. Does that tell you everything you need to know? (Assuming it'll be allowed through. If not, what's the easiest way to list all the settings?)

I still have all the moderation notification emails, with the original emails attached. Can I use those to get the information you need?

But before I start trying to gather together evidence, could we "fix" this problem by setting convert_html_to_plaintext to No? If so, are there any side effects of that we should know about before we try it?

I'm not the owner of the list, and it wasn't my decision to set it to Yes. I'm under the impression that the owner changed it as a precaution once after the list was somehow being used to send out spam. It's my impression that in the years before I had admin access, there have been periods when html was allowed, but I have no idea of the reasons for the earlier changes.
