The 3 lines above are the user's MUA's description of the message.

The lines below here are some but not all of the message headers and
base64 encoded message body.

This is occurring because something in the delivery chain to the user,
presumably the MTA at the user's ISP as there are no Received: headers
below here, has added this Content analysis details: header and
presumably also inserted a blank line ahead of it. The blank line ends
the headers so the remainin headers and body all look like the message
body to the user's MUA.

Since the

Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: base64

headers are below, the base64 encoded message body is not decoded.

This appears to be an issue in whatever adds the Content analysis
details: header with the SpamAssassin report.

The only curious thing is why doesn't this happen with every message, or
perhaps it does, but some message bodies are not base64 encoded and are
thus readable.

This is an issue for the user's ISP. It is not a Mailman issue. The only
part of it that has anything to do with Mailman is Mailman will base64
encode the message body if the message character set is UTF-8, but not
if it is US-ASCII.
