[Mailman-Users] Can't post with thunderbird

[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.

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:

Hi,

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

Thanks for any help in advance,
Johannes
