    Today my server went down. I rebooted it and now all websites work fine but the mail server has given up working. Webmail works actually, but customers cannot receive or send emails from their Outlook, Macs etc.

    How can I solve this problem. It is very urgent. I have more than 100 customers and all of them are calling me.

    Thank you so much in advance.

    Now I want to enter WHM through the link server1.example.com:2087 and says that the DNS address of the server server1.example.com cannot be found.

    Can you login using ssh to run some checks?

    Yes, I can.

    When I try to send a message from Mail in Mac, for instance, it says that the server server1.example.com cannot be found. If you make a ping on server1.example.com it does not respond. So, I think it must be a DNS problem. I'm not sure because I am not an expert.

    So check what services are running like:
    #service named status
    Read the last few lines of the error log:
    tail 150 /var/log/messages

    Hello,

    Your websites are working fine it means the DNS service is running.

    You are facing problem to access WHM using hostname. I think there is issue with hostname.

    First you can check your current hostname which is set on the serve.

    Hello

    Check and ensure that the DNS record for the hostname server1.example.com exists in the zone file of example.com . You can check the DNS health of the domain using the URL intodns.com/.

    Mail delivery issue can be due to multiple reasons. Check the mail log /var/log/exim_mainlog for any mail delivery issues.

    Hello,

    You can try running the following command to rebuild the DNS configuration file:

    Code:
    /scripts/rebuilddnsconfig
    Also, do you have a firewall management utility such as CSF installed on the system? If not, you may want to consider installing a utility such as CSF to ensure your firewall rules are properly managed:

    ConfigServer Security & Firewall

    Thank you.
