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, unfortuanatly no answer solves my problem ;(

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

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

.. and that it should even fallback on topic if all else fails...

But then why doesn't it work? According to the mbox of my archive mesasages 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
