    I hope you don't mind me jumping on this thread. . .
    I'm experiencing the same problem. I have just obtained two VPS servers, both of which are running CentOS 7.3.1611 and I've installed Centos Web Panel on both. I'm currently using the bundled Free DNS Manager to manage the DNS zones.
    On one of the servers (goodserver . com), I can send and receive emails without any apparent problems, but on the other (badserver . com), I can send emails, but I don't receive some emails.

    Using Roundcube with me[at]badserver . com, I receive emails sent from me[at]badserver . com and I also receive emails sent from me[at]goodserver . com.

    goodserver . com is a separate VPS with a different ip address to badserver . com. But I don't receive emails sent via Roundcube from me[at] which is a managed package on cPanel. All three servers are from the same hosting company.

    I've compared the DNS records (held in Free DNS Manager) for and, and apart from domain name details and ip address, they are exactly the same (domain name and ip address are both appropriate for the relevant server.

    netstat and iptables output is the practically the same for both servers and is:
    tcp 0 0* LISTEN 1887/master
    tcp6 0 0 [::]:smtp [::]:* LISTEN 1887/master

    Chain INPUT (policy ACCEPT)
    target prot opt source destination

    Chain FORWARD (policy ACCEPT)
    target prot opt source destination

    Chain OUTPUT (policy ACCEPT)
    target prot opt source destination​
    On, the number is 24672 as opposed to 1887.

    Any suggestions or pointers would be most gratefully received.
    Many thanks
