Every incoming email sent to my Zendesk is suspended

<h2 id="h_01KS0NWV6HDF0X9MA84T9WQ4J1">Issue symptoms</h2><p class="p1">I set up <a href="https://support.zendesk.com/hc/en-us/articles/203663266-Forwarding-incoming-email-to-Zendesk-Support" target="_blank" rel="noopener noreferrer">email forwarding from an external support address</a> to my Zendesk and now every email appears on the suspended view.</p><h2 id="h_01KS0NWV6H8S083PGP5JF4V46R">Causes</h2><p>The cause of these suspended emails usually is an incorrect set of a web form with email forwarding, a spammy sender or an issue with email headers and automations. For more information, see the article: <a href="https://support.zendesk.com/hc/en-us/articles/115009659807-Causes-for-ticket-suspension" target="_blank" rel="noopener noreferrer">Causes for ticket suspension</a>.</p><p>Additional suspension causes include:</p><ul>
<li data-list-item-id="e6ffcd3f38d2ec72aade37ca6019cb0d7">
<strong>Received from support address</strong> indicates that your email server is configured with an external support address, for example, <code>mailto:support@example.com"&gt;support@example.com</code> as the <code>From</code> or <code>Reply-To</code> header in every email forwarded to your Zendesk. These messages are suspended by Zendesk due to the ability to cause mail loops. To resolve this issue, modify the email forwarding on your server to show the email address of the ticket requester email address rather than your external support address in the <code>From</code> or <code>Reply-To</code> header.</li>
<li data-list-item-id="ebf07d6271a6d714707702b96ef4f22d9">
<strong>Automated response email</strong> indicates that the email server is adding an automated header such as <code>Precedence:bulk</code> or <code>Auto-submitted:auto-generated</code> to every email that is forwarded to your Zendesk account. These headers tell Zendesk that the messages were auto-generated rather than created by end users. To resolve this issue, modify the email forwarding on your server to not add either of these headers to forwarded email messages.</li>

What is "Received from a support address" or "Received from support
address"? Why does "Received from a support address" or "Received
from support address" happen? What does "Received from a support
address" or "Received from support address" mean?
</h2>
<p>
This suspension reason indicates that your email server configures
an external support address or customer account as the From or
Reply-To header in every email forwarded to your Zendesk account.
Zendesk suspends these messages due to the ability to cause mail
loops.

What is "Automated response email" or "Automated response mail"?
Why does "Automated response email" or "Automated response mail"
happen? What does "Automated response email" or "Automated response
mail" mean?
</h2>
<p>
This error indicates that the email server adds an automated
header such as Precedence: bulk or Auto-submitted:auto-generated
to every email forwarded to your Zendesk account or ticketing
system. These headers tell Zendesk that the messages are auto-generated
rather than created by end users or customers.

Can I use a web form with email forwarding? Is a contact form
with email forwarding supported? Why does my web form cause ticket
suspension?
</h2>
<p>
No. Setting up a web form or contact form with email forwarding
is not supported and causes expected errors. Instead of email
forwarding with a web form, use the API or tools for sending
Zendesk info to external tools to generate tickets.
</p>
<h2 id="h_01KXDTMJ9JDT3V2KDEF9CSFME6">
Can I use an alias or an email group for my support address?
Is an email group or alias supported for support addresses?
</h2>
<p>
No. Using an alias or an email group for your support address
is not supported. Ensure your support address uses a regular
email address instead.

How do I fix every incoming email or support conversation sent
to my Zendesk getting suspended? How do I resolve external support

</h2>
<p>To resolve this issue, follow these steps:
</p>
<ol>
<li>
Use the API to generate tickets instead of email forwarding
with a web form.
</li>
<li>
Verify that your support address does not use an alias or
an email group.
</li>
<li>
Ensure that the forwarding is at the server level, rather
than the individual settings of the support address.
</li>
<li>Verify your SPF record.</li>
<li>
Ensure that the email header from your email forwarding does
not contain unsupported entries under Automated response
such as Delivered-To, Auto-Submitted, or Autoresponder.
</li>
<li>
Check that you do not use an email address that starts with
noreply@, daemon@, or postmaster@.
</li>
<li>
Verify that the emails do not contain any unsubscribe links.
</li>
<li>Verify that the emails are not automatic replies.</li>
<li>
Take a full page screenshot of one example including the
sender, receiver, and time, and share it with Zendesk Customer
Support if issues persist.
