FAQ
Hello,

One of our list serve administrators is experiencing an issue with one
of her listserves.
Here is her description of the issue. She is sending text to her
listserve which is
a moderated list. She approves the message but as a member of the list, the
email is received with 3 attachments: ATT00001.c, ATT00002.htm, and
ATT00003.c. The administrator has 2 other lists and when she sends text,
she receives them as text. She would like email sent as text to be received
as text. I have checked the configuration settings from her 3 lists, and
the
difference between the 3 is the one that is having this issue is the
moderated.
I would not think this to be the cause of the issue. At first, the
issue was reported
to me that email was sent as html but was received as text so I suspected
the issue to be with the Content Filtering settings. So, I checked all
3 lists and
they are exactly the same.

Just to inform the group, I did check the FAQ archives but have not
found the issue.
Also, we are using Mailman version 2.1.9.

Has anyone seen this and if so, what is the resolution?

Regards,
Darren

    The only time I've heard of anything like this is when there are different
    character sets being used in some of the headers or footers (sometimes space
    characters), thus causing the different parts of the message to be put in
    different MIME body parts (as described in FAQ 4.39 at
    <http://wiki.list.org/x/84A9>).

    You could try deleting all list-specific headers and footers and re-creating
    them, this time making sure that you don't put in any non-ASCII characters.
    Or maybe you've got ASCII characters in there, but there are non-ASCII
    characters in the submitted message, such as accented characters in
    someone's name or signature?

    Other than that, I have no idea how this kind of thing would happen.

    The .htm extension on the middle "attachment" which I assume is the
    message body indicates she is not sending a text/plain message but
    rather a text/html message, and content filtering is not removing the
    html part or converting it to plain text. The other "attachments" are
    probably the msg_header and msg_footer as Brad suggests. The FAQ Brad
    references is the relevant one. The difference between lists may be
    that this is the only one that adds msg_header and msg_footer.

    I may not have this exactly right, but the only way to know for sure is
    to see a raw message from the list or at least the content of the
    three "attachments"

    Yea, it is incorrect to use listserve but it is common amongst our users so
    I have assimilated to use the same terminology :( It is a Mailman list.

    As Brad wrote, I found some non-ascii characters in the introduction
    description
    from the general options for the list so I removed them. I asked the
    list admin to send
    another message to the list. BTW, I asked the admin to add me as a
    member so I can
    see what is happening.
    I may not have this exactly right, but the only way to know for sure is
    to see a raw message from the list or at least the content of the

    If this does not resolve the issue, I will add the attachments in my
    next email to
    the group.

    I have attached the files you requested, as sent to me by the list
    administrator.
    It appears to me what is happening is the list server is sending the
    email with
    3 attachments but displays as 4 parts: there is the message header, the
    text
    version of the email, then an HTML version of the email, followed by the
    message
    footer. I see like a line separator between each part. (I use the
    Thunderbird mail
    client). This does not seem like normal behavior. If anything, there
    should
    be a minimum of 3 parts, not 4.

    Let me know if there is any else you need from me.

    The actual attachments didn't get to the list, but they are as Darren
    describes.

    It appears that the original message to the list is
    multipart/alternative with test/plain and text/html alternative parts.
    The three message parts in addition to the headers are the text/plain
    part, the text/html part and the msg_footer.

    Something is wrong with what is happening to this message. Normally, if
    a message with structure

    multipart/alternative
    text/plain
    text/html

    is sent to a list and content filtering doesn't remove eather
    alternative or collapse alternatives, the msg_footer will be added as
    a separate part and the final message will look like

    multipart/mixed
    multipart/alternative
    text/plain
    text/html
    text/plain

    I.e. it will be converted to a multipart mixed message with two parts -
    part 1 being the original message parts and part 2 being the footer.
    In your case, it appears that the final message structure is

    multipart/mixed
    text/plain
    text/html
    text/plain

    instead.

    What Mailman version is this?

    What are the list's content filtering settings?

    What is the raw message with all headers?
    In Tbird, select the message and then File->Save As->File or just
    ctrl-S, and give it a name with a .txt extension. Then you can attach
    that .txt file to a list post.

    What Mailman version is this?
    2.1.9
    What are the list's content filtering settings?
    Should Mailman filter the content of list traffic according to the
    settings below? No
    Remove message attachments that don't have a matching content type.
    Leave this field blank to skip this filter test.

    multipart/mixed
    multipart/alternative
    text/plain

    Should Mailman collapse multipart/alternative to its first part
    content? Yes

    Should Mailman convert text/html parts to plain text? This conversion
    happens after MIME attachments have been stripped. Yes

    Action to take when a message matches the content filtering rules.
    Discard

    The Content Filtering settings are the same across all 3 lists the admin
    owns but only this one is it working
    incorrectly.
    What is the raw message with all headers?
    In Tbird, select the message and then File->Save As->File or just
    ctrl-S, and give it a name with a .txt extension. Then you can attach
    that .txt file to a list post.
    I see that my attachments did not come across so I have attached the raw
    message
    removing only some private information. The owner forwarded to me a copy of
    the email sent to the list.

    OK.

    What are the list's content filtering settings?
    Should Mailman filter the content of list traffic according to the
    settings below? No

    So content filtering is off and not involved.

    OK.

    Thanks, but the forwarded message doesn't help much. It appears to be a
    forward from MS Outlook of the received message. What I would need to
    see is the raw message. I don't know how to get that from Outlook. In
    Outlook Express, you can right-click the message in the message list
    pane and then select Properties->Details->Message Source and then
    select and copy the entire message source and paste it into notepad,
    but I have no idea if this would work in Outlook.

    What I can see is the part that says "Womens_Center" looks like
    msg_header so that both msg_header and msg_footer are added and the
    result should look like

    multipart/mixed
    text/plain
    multipart/alternative
    text/plain
    text/html
    text/plain

    It is possible that this is in fact the structure of the message and
    Outlook thinks that the first text/plain part is the message body and
    everything else is an attachment, in which case, it's realy an Outlook
    issue, but that wouldn't explain why the other lists are OK unless
    they don't have msg_header.

    I do have another idea. You said the difference here is the message is
    held for moderation and approved. Does this Mailman instance have some
    kind of patch that enables editing held messages before approval? If
    so, I think that's where the problem lies.

    The other 2 lists do not have message headers. The issue appears to be an
    issue with Outlook, in combination with the message header from the list.
    The Exchange administrator showed me what it looks like in Outlook and
    it was as I suspected: the message header "womens_center" is the message
    body and everything else are attachments. I am going to suggest to the
    administrator of this list to remove the message header. I think this will
    resolve this issue.
    I do have another idea. You said the difference here is the message is

    Is the non-working list the only one with a msg_header as well as a
    msg_footer? If that is the case, try removing the msg_header
    completely and see if that helps.

    If that is not the case, does this Mailman instance have any
    modifications to allow editing a post from the admindb interface prior
    to approval?

    Did that. This apparently resolved the issue as the admin owner is happy.
    However, I am not totally convinced that it is a mail client issue. I
    am seeing 4 parts
    in my Thunderbird mail client:

    plain text (header)
    plain text (body)
    html (body)
    plain text (footer)

    Why would mailman be sending plain text and html attachments? When the
    header is removed, my Thunderbird mail client shows the email message
    as plain text and one attachment, the footer.

    My comments about this are below. Note to list - the attached message
    was removed by content filtering, but I received it in my direct copy.
    I have summarized the saliant points in my reply.

    What you are seeing is consistent with the attached message.

    Why would mailman be sending plain text and html attachments? When the
    header is removed, my Thunderbird mail client shows the email message
    as plain text and one attachment, the footer.

    Did the message below come directly to you from the list or was it
    forwarded to you. If it came directly from the list, I don't
    understand it. Note that the second through fourth parts all have
    headers of the form

    Content-Type: text/plain; name="ATT00001.c"
    Content-Description: ATT00001.c
    Content-Disposition: attachment; filename="ATT00001.c"; size75;
    creation-date="Thu, 15 Jan 2009 11:50:12 GMT";
    modification-date="Thu, 15 Jan 2009 11:50:12 GMT"

    Mailman did not create these headers. What appears to be going on is
    that this message is received from the list and opened in an MUA that
    identifies the first part as the message body and the remaining 3
    parts as attachments. The message is then forwarded from that MUA
    resulting in the message you attached.

    In particular, the last part is the list's msg_footer, and it has part
    headers:

    Content-Type: text/plain; name="ATT00003.c"
    Content-Description: ATT00003.c
    Content-Disposition: attachment; filename="ATT00003.c"; size!8;
    creation-date="Thu, 15 Jan 2009 11:50:12 GMT";
    modification-date="Thu, 15 Jan 2009 11:50:12 GMT"
    Content-Transfer-Encoding: base64


    Mailman would have created that "attachment" with only the headers

    Content-Type: text/plain
    Content-Transfer-Encoding: xxx

    with the possible addition of a charset parameter on the Content-Type:
    header, and most likely 7bit or 8bit Content-Transfer-Encoding:.

    All the other headers and the name= parameter were added after the
    message left Mailman.
