[Mailman-Users] Message text not showing up in digests or archives - Skipped content of type multipart/alternative

A sporadic number of messages in digest and archives are showing up with out the original message text and instead "Skipped content of type multipart/alternative" is showing up. I did a search and found a few others had experienced this problem some years ago but there wasn't any real follow up to the original posts, none that were helpful anyway. I was hoping folks on this list might have some insights. Thanks so much.
