GNU Mailman

Cannot post to mailman lists with thunderbird

Asked by Johannes Wienke

Hi,

I got a strange problem with a mailman mailing list hosted at kde.org. I'm registered at that list and also got access to the admin interface. The problem is that if I post a message with thunderbird it gets into the archive but isn't delivered to the subscribers of the list, including myself. This is independent of the smtp server or account I use for that list. If I post a message with any other mail client (gmx web interface, kmail) everything works as expected.

As far as I can see this even happens at the mailman-users list, cause this message didn't get on there, too.

Has anyone got an idea what could cause this problem? The admins of that list don't have a clue either.

Here is the mail source code as it is sent by thunderbird:

Message-ID: <email address hidden>
Date: Sat, 24 Oct 2009 15:54:01 +0200
From: Johannes Wienke <email address hidden>
User-Agent: Thunderbird 2.0.0.23 (X11/20090817)
MIME-Version: 1.0
To: digiKam developers room - digiKam: Manage your photographs as a professional with the power of open source <email address hidden>
Subject: Magic Numbers
X-Enigmail-Version: 0.95.6
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Content-Transfer-Encoding: 7bit

Hi,

<more email contents>

I already deactivated enigmail, switched to encoding us-ascii, removed format=flowed... Nothing helped.

Thanks for any help in advance,
Johannes

If the message is archived, it has reached the list and it should be delivered as long as Mailman's OutgoingRunner and the MTA are working which must be true if other posts are delivered. I can't see how this could be caused within Mailman.

There is an issue with the above mail. The long display-name contains a colon ':' and therefore must be quoted as

To: "digiKam developers room - digiKam: Manage your photographs as a professional with the power of open source" <email address hidden>

I don't see how this alone would cause mail loss in Mailman, but it could affect other parts of the system.

In the case of the <email address hidden> list, your post is not archived either, and the reason is most likely that it is held for moderation as all new-member posts are. You aren't notified that your post is held, and there have been delays of up to two weeks lately in approving held posts.

Your issue will have to be investigated by the admins at kde.org. Further investigation requires access to Mailman's and the MTA's logs.

Thank you, the colon is the problem. Without it the mail is delivered.
