Hello,

Thanks. I have resolved the mentioned issue.
When I was sending a mail to one of email id, server generating 10-15 logs and showing mail is delivered successfully but mail was not reaching in to inbox. I logged into WHM > go to Edit DNS Zone > select domain name (check the setting), just uncheck the Automatically Detect Configuration: Local (recommended) and select/check the Local Mail Exchanger option from WHM.

Thanks,
Imran Khan.
