thinking that I could turn out for the night with a well-deserved drink, I
got this from vger.kernel.org:

SMTP error from remote server for TEXT command, host: vger.kernel.org (209.132.180.67) reason: 550 5.7.1 Content-Policy reject msg: Wrong MIME labeling on 8-bit character texts.

Is there *anybody* who could give me a clue what this means?

Have you tried postmaster (at vger.kernel.org)?

For the record, I tried to use `git send-email` to send out the
announcement for the very first time, and the headers of the mbox file I
fed to that command read thusly:

The only problem I could *possibly* imagine is this UTF-8 bullet character
used in the enumerations in the mail body:

	 • [...]

The above header you showed says "Content-type: text/plain;
charset=UTF-8" and I am hoping that this response to you will go out
with that labelling back to vger, so we will hopefully see if that
bullet is the culprit (I doubt it, though).  I have no specific
suspect at this point yet, other than "somebody that gets your
message from send-email and passes to vger may be mangling it".
