OT: I have received a series of duplicate emails.

[Budge]

Hi, just received a series of duplicate emails in the "Compulsory
podcasts - In Our Time" thread. Is there a server issue or is it at my
end? Seems to have abated for now but it has happened before.

I have had an almost opposite problem for the last week or two. I still
receive posts from other list server members, but I have not been
receiving copies of my own posts. I checked my profile, and there does
not appear to be any change in my settings.

When I first checked, it told me I had a bounce score of 2 (out of a
maximum of 5). That was consistent with the 2 messages I had sent
during the previous few hours for which I had not received a copy. The
bounce score must be being reset after a time, because at the weekend it
was 1, but it is now 3.

Is there any way I can retrieve the bounce messages so I can see what is
going wrong?

I have not seen any duplicates (expect when people reply to me as well
as the list).

Best wishes
Richard

Some other people aren't receiving your messages either. It's because
the zoho.com domain publishes a DMARC record promising that mail from
that domain will only ever come *directly* from its own servers, and
that @zoho.com users will never post to a mailing list.

Some mail servers (including your own) look at that DMARC record and
then refuse to accept the "fake" mail from you, when the mailing list
server sends it on.

This is (one example of) the specific error I see in my logs:

2018-11-18 16:55:57 +0000 1gOQMQ-0004Y2-6x ** ***@zoho.com R=lookuphost T=verp_smtp H=smtpin.zoho.com [204.141.42.120] X=TLSv1.2:ECDHE-RSA-AES256-SHA:256 CV=yes: SMTP error from remote mail server after end of data: 550 5.7.1 Email rejected per DMARC policy for zoho.com

Yes, DMARC is a problem for mailing lists, I had a similar problem for some lists I run using Mailman:

Yeah, there are hoops that a mailing list can jump through so that it
works around this problem for mail domains which disavow their own mail
because they didn't realise how email works.

Alternatively, you can say "here's a nickel, kid. Get yourself a
competent email service".¹

Thanks for the explanation of what is going wrong. I need to do some
reading about DMARC and look at some headers.

George

Thanks for the link about DMARC and Mailman.

Thanks for pointing out that Gmail is treating my posts as spam. From
what David says users are not receiving my posts at all.

I have now changed my profile so that
Receive your own posts to the list?
is set to No.
That should avoid the problem of bounced messages when my posts are sent
back to me. I only need it for confirming that a message has not been
rejected for inclusion of HTML, or Reply-To violation. I can do that
from the archive.

That won't help where other users are not receiving my posts or having
them flagged as spam. I'll ask Zoho support what they have done to
implement DMARC (presumably it has changed in the last couple of weeks)
and whether there is any mechanism for opting out.

Best wishes

This one went straight to inbox not spam

What was different about that one was that I had set
Receive your own posts to the list?
to No. It seems weird that setting whether or not a post is sent to me
affects what other users receive.

FWIW, I think I've seen them all.

I am using Gmail (via GSuite) and every single message you (RS) send
to the list goes in my spam folder.

Every other message from anyone else goes correctly into my inbox
