The company I currently work for uses a cPanel interface on their server. Currently we are having some issues on this server interface to correct the email SSL host name. Searching around I found a company who specializes in cPanel management. cPanel Server management suggested that we edit the /var/cpanel/ssl: However, we are still having some issues with the courier-imapd-DOMAINS. Does anyone have any suggestions how we can get around this and fix the issues?
Did you try asking for support on the cPanel forum? They are pretty good at giving support to people who use their software.
As already you have cpanel license. You can directly ask the issue related to cpanel and its configuration with cpanel technical engineers here https://tickets.cpanel.net/review/login.cgi . Just register and submit the server details and provide them issue you are facing .. Within few hours it will be resolved by them ...
