Just to clarify, I assumed Gnus was doing the conversion to octet-stream
but I never verified that.

Heh, interestingly enough that patch was sent from redhat.com:

https://lore.kernel.org/all/[email protected]/

Is that just a coincidence or are Redhat servers doing something
strange? If you find out, do let me know. I'm very curious :)

The emails I got from linux-mm mailing list do not have Content-Type either,
but the ones I got directly from my git-send-email have it. David is in the
cc list, so the emails sent to him should have Content-Type.

FYI, I sent the emails using git 2.35.1 via fastmail.com and have
transferEncoding=quoted-printable.

It is strange. Also mails from Andrew result in the same,
unusable/unreadable mails in my inbox. :(

Right now I assume that Mimecast servers try to auto-detecting and
adding "Content-type:", and somehow mess up. And I do think that it
doesn't always mess up; some patch content (encoding?) seems to trigger
that.

I assume I received them without a Content-type, or mail servers
stripped them, and Mimecast servers (which RH uses) fail to auto-detect
and add a wrong Content-type. Wouldn't be the first time that Mimecast
messed with mail encodings etc, unfortunately.
