answer from Zoho (was: Re: the future of the computer world (was: Re: Google Gmail mailing list bounces))

I got an answer from Zoho after pointing to the
thread where it was said they were incorrect
blaming Gmail for what happened. They write

    XXX

    Hello,

    Apologies for the trouble. We explained
    this during the initial conversation.

    When an email sent through zoho.com/zoho.eu
    is not authenticated it could possibly
    be rejected.

    Meanwhile, we would like to inform you that
    we have made some changes on our end for
    the domain zoho.com to prevent abuse of our
    email service through zoho.com. We have
    listed the same in the below post for your
    reference:

    https://help.zoho.com/portal/community/topic/preventing-spam-emails-using-zoho-com-enforcing-spf-dkim-and-dmarc-for-zoho-com-accounts

    Kindly try sending emails only through Zoho
    Webmail or from an Authenticated SMTP
    server to avoid such inconveniences.

    Hope this helps. Do write to us for
    any queries.

To this, I, not bothering to hide my annoyance
with the whole affair and with them in
particular, so to this I answered this, hoping
I interpreted the material presented here in
help-gnu-emacs/gmane.emacs.help in a correct
way:

It will _always_ be rejected when sent from
a mailing list or a newsgroup to a receiver who
complies with your own policy. You can confirm
this with the following commands:

$ host -t txt _dmarc.zoho.eu
_dmarc.zoho.eu descriptive text "v=DMARC1;
p=reject; sp=reject; fo=0;
rua=mailto:dmarc.reports.eu@zoho.eu;
ruf=mailto:dmarc.reports.eu@zoho.eu"

and

$ dig _dmarc.zoho.eu txt +short
"v=DMARC1; p=reject; sp=reject; fo=0;
rua=mailto:dmarc.reports.eu@zoho.eu;
ruf=mailto:dmarc.reports.eu@zoho.eu"

Did you read this thread? It is explained in
full [1].

Only that link doesn't work for me: it
shows a blank tab.

I'm not ever going to use your web interface.
I've been using Emacs Gnus for ~10 years now
and put many man hours into configuring and
extending and learing to use it to my liking.
If I had known one was supposed to use the
web interface with Zoho, I would never have
registered in the first place.

Anyway now they have put a fix in the
help-gnu-emacs/gmane.emacs.help machinery so
when I send to them, it is resent by them, but
without the DMARC policy of yours, so it'll
still reach Gmail and other users.

Is this a correct understanding of what
just happened? If it isn't - too late,
I already sent him the reply :)
