[Bug 1787690] Re: Mailman rejects multipart content from Gmail/android

[Mark Sapiro]

This is the correct tracker for Mailman 2.1 issues.

The headers at
https://bugs.launchpad.net/mailman/+bug/1787690/comments/2 are only the
message headers and only say that the message's Conternt-Type: is
multipart/mixed. If I send a message from Gmail on my android phone it
has the following MIME structure.

multipart/alternative
    text/plain
        the plain text alternative
    text/html
        the html alternative

I suspect the message you are looking at from the list has structure

multipart/mixed
    multipart/alternative
        text/plain
            the plain text alternative
        text/html
            the html alternative
    text/plain
        the list footer

I can download the
https://bugs.launchpad.net/mailman/+bug/1787690/+attachment/5181125/+files/Selenetest%20Test%20subject.msg
attachment, but I can't open it with anything that renders it properly.
'file' tells me "Composite Document File V2 Document, Cannot read
section info".

Note that you can't use wildcards in pass_mime_types, but you can
specify a main type without a subtype. I.e., this

multipart
text

in pass_mime_types will accept any text/* elemental parts within any
multipart/* parts.

Also note that Content filtering -> filter_action controls what is done
with a message from which content filtering removes everything and there
should always be a Message discarded or Message rejected message in the
vette log in any case.

Is there anything in Mailman's error log?

If you have problem posting a raw message, just send a message from your
android gmail app with Subject: Bug 1787690 to mark at msapiro.net.
