    Hello,

    I have a problem with email delivery. My email is not sent. When I saw the logs :

    Sender address rejected: Domain not found

    I've read the following post :

    Why didn't my email get delivered? or where did my email go?
    Reading and Understanding the exim main_log
    Sender, sender host and failing Blacklisted SMTP IP addresses?

    and tried to turn off sender verification setting but it's not working.

    Here is my full log :
    [Removed - Please use example domain names and IP addresses]

    Appreciate your help.

    Thanks

    Make sure domain name used in the recipient address is registered and active, check here : who.is

    If its active then paste here logs or bounce back message.

    Hello :)

    You can use a website such as IntoDNS to verify the domain name uses MX records that resolve to the cPanel server. Also, are you able to reproduce the issue when sending from the cPanel server to remote mail servers such as Google/Yahoo, and vice-versa?

    Thank you.

    Hi All,

    Thank you for your reply. After checking hostname of my server, it looks like that hostname revert back to default hostname from AWS so I can't send email. When I change the hostname, I can send email again.

    Thank you for your help.
