[Mailman-Developers] Thread not shown allthough In-Reply-To present

[Bram de Kruijff]

Hi all,

allthough I found a lot of questions about why mailman/pipermail
doesn't show threads when mail is transferred by outlook/exchange
in the archives, but unfortuanatly no answer that solves the 
problem ;( 

I read in one of the posts that threading is done based on;

- Message-ID
- References
- In-Reply-To

But then why doesn't it work? According to the mbox of my archive
messages sent by outlook/exchange users don't contain a References
header but DO contain Message-ID and In-Reply-To headers.
In the same archive messages sent with mutt do contain a References
header and are shown threaded

Does pipermail realy check the In-Reply-To?
Is something wrong with the format used? eg;
 
In-Reply-To: <6C9EC88CAD726B49A43EE2E2B2AD6E5383E93C@maul.gx.nl>

any ideas?
thanks in advance!

Bram
