Hi Rouven,

I am using git send-email, but the MS-Exchange server "improves" the messages.
In my outbox on the server (OWA) they look good and do not have the footer.

Please find original mboxes attached.
Michael Olbrich gave me the tip, that an attached mbox is as easy for him as inline.
Hopefully this is true for Sasha, too.

Regards, Denis
