I have one listserv subscriber, who is signed up for the regular (not digest) version. He has been intermittently getting these odd versions of messages. When he gets this format, he does not get the regular html version. Most of the messages come through just fine. I have a number of other ones he has sent me if you need to see them. I also have 9 other subscribers on me.com, whom I have not gotten complaints from.
See my comments inline below.

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.
