record to his dns earlier but it didn't help so far. <br>
<br>
For those who are interested, I created a knowledgebase article
for our site on DMARC, what it is and how to create one here:<br>

cPanel I give instructions in the article.<br>

is pretty confusing to even relatively geeky people. DMARC
(Domain-based Message Authentication, Reporting and
Conformance) is an email authentication protocol you can
add to your DNS zone (your domain's entry in the web's
"phone directory" that translates a domain name into
something a computer can use for getting you to a website
or passing along an email, etc.).<br style="box-sizing:
border-box;">
<br style="box-sizing: border-box;">
It's designed to give email domain owners the ability to
protect their domain from unauthorized use, commonly known
as email spoofing. The purpose and primary outcome of
implementing DMARC is to protect a domain from being used
in email compromise attacks, phishing emails, email scams
and other cyber threat activities.<br style="box-sizing:
border-box;">
<br style="box-sizing: border-box;">
It's also a way of showing other mail servers that your
email is reputable.</span></p>

a DMARC Record</strong><br style="box-sizing:
border-box;">
<br style="box-sizing: border-box;">
To create a DMARC record, if you have access to your DNS
zone records, create a new TXT record with the name
_dmarc.yourdomain.com<br style="box-sizing: border-box;">
and content that looks something like this<br
style="box-sizing: border-box;">
v=DMARC1;p=reject;sp=none;adkim=r;aspf=r;pct=100;fo=0;rf=afrf;ri=86400;ruf=<a class="moz-txt-link-freetext" href="mailto:me@mydomain.com">mailto:me@mydomain.com</a><br
style="box-sizing: border-box;">
<br style="box-sizing: border-box;">
Obviously this is not something you can create out of the
blue. cPanel, the world's most widely used control panel
for web hosting that we use at Itabix, now has a built in
DMARC creation tool in the DNS zone editor (we'll walk you
through that below), or you can use a DMARC generator on
the web however most of the DMARC generators are also
difficult to understand. We really like this one:<br

</font></font><font face="Helvetica, Arial, sans-serif">Remember
to set the policy to Quarantine (set aside for additional
processing) or Reject (get rid of it) because, as Larry said,
setting it to do nothing won't cut it with a lot of mail servers
and you'll still be rejected.<br>

<div dir="ltr">It is probably the lack of a DMARC record that is
causing it. In that past year, I have seen several providers
start blocking email from domains that do not have a DMARC
policy.
<div>I also recently found that the DMARC policy must
specifically have a quarantine or reject policy. When I added
a quarantine policy to our existing DMARC, many email
recipients that were getting rejected are now being accepted.
