Problems with mail delivery

Post by kompresja » Tue Mar 29, 2016 2:20 pm

Hi, I have added our domain to Mail module using all steps necessary to verify domain... However, some users/email addresses are not using our Onlyoffice service. We are finding issues to end them messages. There is Undelivered Mail Returned to Sender error:

This is the mail system at host
I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to postmaster. If you do so, please include this problem report. You can delete your own text from the attached returned message.

The mail system
<>: user unknown

What is funny, they can send us a message :)

Any ideas how to manage it?

Most probably you have added the domain, but haven't created the mail boxes, that you have had earlier on ONLYOFFICE portal.
That's why those old mail boxes stoped working, because there are no such mail boxes on our server.

So you should connect the domain to ONLYOFFICE and after that create the mail box
In this case the mails receiving and sending will be working correctly.
