Is not authorized to relay messages

Postby Jhonmicky » Wed Oct 16, 2019 8:49 pm

Hello everyone,,
I am using Zimbra Collaboration 8.8.8.GA.2009 Open Source Software for Mailing solution. My Mail server is working perfectly for all other domains and I had also created all DNS Records correctly. But when I am trying to send a mail to domain I will get an error.
From many days I am facing this issue with one of the Office 365 Domain which I am unable to send messages to domain. When I am sending the mail to domain I am getting below error saying dkt test
"Your message to couldn't be delivered.
sainath is not authorized to relay messages through the server that reported this error."

Sometimes I will also get the different error

"Your message:
Subject: Test Mail

Could not be delivered because of

Server refused mail at END OF DATA - 554 5.4.14 Hop count exceeded - possible mail loop ATTR34 []

The following recipients were affected:"

Would someone help me in resolving this issue. Its a payment gateway so, I need to get a solution for this on priority. Thank you in advance.

If you need any additional information. Please let me know.
