What does your list do to this mail. I.e. have you set from_is_list or 
dmarc_moderation_action to Wrap Message?

Actually, the most likely explanation is the list has set Non-digest 
options -> msg_header, and the incoming message (after content 
filtering) is other than a single text/plain part. This will cause the 
msg_header to be added as a separate MIME part preceding the rest of the 
message. If that is the reason, you may be able to adjust the list's 
content filtering using things like pass_mime_types, 
collapse_alternatives and convert_html_to_plaintext to ensure the 
filtered message is a single text/plain part.

However, if you want to allow HTML, and or attachments, you will need to 
ensure that Non-digest options -> msg_header is completely empty, or use 
a mail client that is better at displaying inline text in line.
