No, I did use firefox with the settings which I found at
https://www.kernel.org/doc/html/latest/process/email-clients.html#email-clients
I think all that is wrong with the message body is it is base64 encoded, and all the
lines end with CRLF, and it seems the CR is the trailing whitespace.
I think the Character Encoding/UTF-8 does not work right with
Exchange Servers.
What Character Encoding would git send-email use? UTF-8?
So I will try to send the patches again, with 7-bit encoded message bodies.
Actually it will be quoted-printable, but I do not use any umlauts.
So for the records, I did open about:config in the firefox preferences,
and change:
mailnews.send_default_charset from UTF-8 to ISO-8859-1
that I have already done before, but it was not sufficient:
mailnews.send_plaintext_flowed from true to false
mailnews.wraplength from 72 to 0
Thanks
Bernd.
