Mail not receiving



Hello I have configured the Email Server. I can able to send the Emails to external domains( and internal domains( but i am not able to receive the emails.



it depends on how the mailflow should work for your scenario.
One typical approach is to retrieve the emails with Fetchmail.
In case you want to receive your messages directly you have to make sure that your server is reachable on port 25 to the public internet and you have to configure a MX-record on the public DNS for your domain pointing to your server.

In case you have already chosen your method to receive emails and there are still problems please check /var/log/mail.log and post the relevant lines.
