[Mailman-Users] Discard mystery

[Sebastian Hagedorn]

Hi,

we're running Mailman 2.1.9 and can't upgrade because our Python is too 
old. Today we had an issue with a message that was sent by our secretary to 
our staff list. Her message kept being discarded by Mailman and I can't 
find the reason. The list in question has all filter settings either turned 
off or set to "Hold". She sends messages to that list regularly and there 
haven't been problems like that before. She *does* use Outlook 11 as MUA 
and sends her messages as HTML (with multipart/alternative), both of which 
I frown upon, but the MIME filter is off and it's never been a problem 
before. All I can find in the logs are these lines:

Mar 04 12:27:07 2009 (20263) Message discarded, msgid: 
<000301c99cbc$262fa090$2c515f86 at ad.unikoeln.de>
Mar 04 13:43:43 2009 (20263) Message discarded, msgid: 
<000601c99cc6$d94b05c0$2c515f86 at ad.unikoeln.de>
Mar 04 13:50:59 2009 (20263) Message discarded, msgid: 
<000001c99cc7$dd85d3d0$2c515f86 at ad.unikoeln.de>
Mar 04 13:56:34 2009 (20263) Message discarded, msgid: 
<000001c99cc7$401fca60$2c515f86 at ad.unikoeln.de>

That's the same message, resent over and over to no avail. I had her send 
it to me privately and it arrived OK.

Is there any way to figure out why Mailman discarded it? Its content is 
innocuous, so I'd be willing to redirect it to Mark or whoever might be 
interested in investigating this ...
