Hi, Paolo

Can you take a look at this patchset? It has been quite a long time
since we spotted this problem...

friendly ping ...

friendly ping ...

I can't speak for Paolo, but I've mentioned before that the majority
of your messages end up in my spam. That's still the case, in fact
I just marked maybe 10 of them as not spam.

You really need to get this issued sorted out, or you will continue
to have patches ignore because folks may simply not see them.

Hi,

Thanks for your notice.

Is it just me or do you see someone else's messages from *huawei.com
end up in spam? I tried to seek help from our IT support, however, they
didn't find anything unusual...

So actually I have noticed that a lot of (valid) email from huawei.com (not
just you) ends up in the spam mailbox. For me direct messages usually pass
(likely matching SPF records for originating mail server save the email
from going to spam) but messages going through mailing lists are flagged as
spam because the emails are missing valid DKIM signature but huawei.com
DMARC config says there should be DKIM signature (even direct messages are
missing DKIM so this does not seem as a mailing list configuration issue).
So this seems as some misconfiguration of the mails on huawei.com side
(likely missing DKIM signing of outgoing email).

SPF/DKIM was indeed a problem earlier for yukaui patches, but I don't
see that anymore. Maybe it's still an issue for some emails, from them
or Huawei in general?

Hum, for me all emails from Huawei I've received even today fail the DKIM
check. After some more digging there is interesting inconsistency in DMARC
configuration for huawei.com domain. There is DMARC record for huawei.com
like:

huawei.com.        600    IN    TXT    "v=DMARC1;p=none;rua=mailto:dmarc@edm.huawei.com"

which means no DKIM is required but _dmarc.huawei.com has:

_dmarc.huawei.com.    600    IN    TXT    "v=DMARC1;p=quarantine;ruf=mailto:dmarc@huawei.com;rua=mailto:dmarc@huawei.com"

which says that DKIM is required. I guess this inconsistency may be the
reason why there are problems with DKIM validation for senders from
huawei.com. Yu Kuai, can you perhaps take this to your IT support to fix
this? Either make sure huawei.com emails get properly signed with DKIM or
remove the 'quarantine' record from _dmarc.huawei.com. Thanks!

Of course, I'll try to contact our IT support.

I second that, pretty much every email has been going into spam since, I
guess you just had a few lucky ones. Looks like Jan is right, it's a
server side configuration error that's causing this, and it's still
happening
