Can't send email

[WilliamDEdwards]

Hello,

I have a problem with my DirectAdmin installation. New installation running on CentOS 7. Domain is "examplemail.com" - it can receive email, but can't send it. Immediately after sending an email from either a mail client or webmail (Roundcube), we get the following error:

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: 

[email protected]

Reporting-MTA: dns; web02. directadmindomain.com 

Action: failed 
Final-Recipient: rfc822;w.d.edwards@ directadmindomain.com 
Status: 5.0.0

(Regardless of the email address.)

tail -f /var/log/exim/mainlog 
[email protected] R=lookuphost defer (-1): remote host address is the local host

[root@web02 custombuild]# exim -bt directadmindomain.com 
LOG: MAIN 
remote host address is the local host: web02.directadmindomain.com (while routing < [email protected]>) 
directadmindomain.com@web02. directadmindomain.com cannot be resolved at this time: remote host address is the local host 

[root@web02 custombuild]# exim -bt google.nl 
LOG: MAIN 
remote host address is the local host: web02.directadmindomain.com (while routing <google.nl@web02. directadmindomain.com >) 
[email protected] cannot be resolved at this time: remote host address is the local host

What's happening?

Thanks
William

So the domain is directadmindomain.com or examplemail.com?

Is the domain valid? Provide a valid domain, also, why the logs you're posting have "web02. directadmindomain.com" with a space? Is this a mistake while you were changing the hostname or is the actual error in your hostname?
