Assuming Content Filtering is Off, the only thing Mailman might be
doing to the content is wrapping it in another MIME level to add list
header and or footer. You could try removing any msg_header and/or
msg_footer if you have any.

If this doesn't fix it, you need to diff the raw messages from direct
Cc: and from the list and see what, other than the obvious top level
headers, is different.

One possibility is if the original message HTML contains very long
lines, one of the MTAs on the path to/from Mailman might be dropping
something.
