You sent a text/plain, but you used iso-8859-1 as your character set,
and you included binary characters. That got encoded as
quoted-printable when it was sent, and that was preserved when the
message was transmitted back out.
Now, I'm not an expert in the workings of the underlying MIME or e-mail
library code in Python that is used by Mailman, but I suspect that any
non-USASCII characters in any of the input messages will force all the
digests to be processed as MIME and not plain text. Unfortunately, for
a language like French, that poses a problem since there are so many
accents you have to account for.
Now, Python is written by a very international community speaking many,
many different languages, and to a somewhat lesser degree the same is
true of Mailman. So, we are very sensitive to language and character
set problems and we do everything we can to try to avoid causing
problems for anyone else. But that means we *don't* take a "just send
eight" approach to transmitting messages, and instead we actually try to
"Do The Right Thing". Unfortunately, sometimes not everyone agrees on
what that "Right Thing" is.
Unfortunately, we really don't have all the information here that we
need. We do see that the outgoing message gets wrapped up in a
multipart/mixed, but we don't see what might have caused that to happen.
I will also add that qmail is not one of my favourite MTAs, because I've
seen more than a few problems caused by it (and I'm not very popular
amongst the qmail communities). But I'm also aware that plenty of sites
out there are using qmail on a daily basis without any problems, so I
won't even talk about pointing the finger that direction until we've
eliminated all other likely possibilities.
If you want to send me a complete, unredacted copy of the message in
question (with all headers intact), I'll be glad to take a look at it
for you and see if I can spot anything obvious. Alternatively, if you
like I can subscribe to your "liste" and we can try out some things that
way. All I ask is that you keep in mind that I don't speak or read
French, despite of the fact that I lived in Belgium for nearly eight
years and my wife and I moved back to the US just a couple years ago.
