Email sent to a domain are never delivered and my customer receive back an email with:
-----Message d'origine-----

Envoyé : 17 octobre 2019 14:39

Objet : Mail delivery failed: returning message to sender
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
f.ray@DOMAIN.com
a.cole@DOMAIN.com
And in an attachment there is a txt file containing:
Reporting-MTA: dns; us205.siteground.us
Action: failed
Final-Recipient: rfc822;a.cole@DOMAIN.com
Status: 5.0.0
Action: failed
Final-Recipient: rfc822;f.ray@DOMAIN.com
Status: 5.0.0
Any idea what's going on?
Ask the client to execute and report on the tests of MXToolbox Email Deliverability and click "View your full deliverability report" in the received email report, and also do the dnslytics email-test.
