It could be an MTA issue, but it seems to me more likely to be an MUA
issue. The reason I think it is not as likely to be an MTA is if the
original is Format="flowed", it would have no long lines so there would
be no reason for an MTA to do anything to the message in transmission.

It is clearly not a Mailman/Python issue, at least with the versions in
use by this list, since the OP as delivered to me from the list and
viewed with Thunderbird did not show any spurious "!" or line break in
the "before" example text.
