Comment 7 for bug 557995

I actually did a simple test of the latest patch and it has issues.

Things like '<' and '>' in headers become html entities so you wind up with headers like

Message-ID: &lt;....&gt;
To: My List &lt;<email address hidden>&gt;

in the delivered post which don't work well for replies.

More significantly, this will really only work for messages which are single part text/plain. For multipart messages, all part headers will be lost and all part contents will be collapsed into one part.
