A subscriber to a mailing list I administer has been sending 8bit UTF-8 encoded mail, with no further quoted-printable / base64 / etc. encoding. This is handled fine by my MTA and MUA, but Mailman seems to have trouble with it. When mail is sent out from Mailman, the « character is replaced by ??.
Is this a bug, or is there just a configuration option or something I need to set? I couldn't find anything in the documentation.

It works for me. I created this message

and posted it to a test list. The message was delivered and archived. The delivered message had the list footer added and was base64 encoded, but in both the delivered and archived message, the « character was intact.
In what other ways does Mailman modify the message. Does it add a msg_header and/or msg_footer, if so, are they added to a simple text/plain message body or is the message more complex so they are added as separate mime parts. Does content filtering remove anything?

Based on the symptoms, I'm guessing this means the SMTPUTF8 extension. Mailman is not prepared for this as far as I know. That is, Mailman expects that the headers will be ASCII, possibly MIME-encoded.
I'm guessing the problem is that either the host MTA or Mailman's LMTP server doesn't handle SMTPUTF8 negotiation correctly, but I do not have time to analyze for some days.

Your message doesn't have UTF-8 in the *header* as far as I can see.

True. I assumed the issue was with a non-encoded 8bit message body. If the issue is with a header, e.g. text in the Subject:, I didn't test that.
