Hi,
https://list.open-mesh.net/pipermail/b.a.t.m.a.n/2008-September.txt.gz
If I look at this file I agree with you that there is no In-Replay-To. But the email header is normaly much longer. So we can see this if you create a new message for the list (not a reply). The mailing list modifies the emails and removes a lot of header entries.
Perhaps the mailing list has a problem with multi-part email. Have you tried to send new emails without attachments/pgp? If it is working than the mailing ist has a problem with that and attachments should be avoided.
