Automatically create proxy subdomain DNS entries in WHM.
This can be enabled on the Tweak Settings page.
Enabling this option will allow WHM to automatically create DNS entries for the following 4 subdomains for every user’s account (where example.com stands for the user’s domain):
* cpanel.example.com
* webmail.example.com
* webdisk.example.com
* whm.example.com
These subdomains allow users to easily access the features included with a cPanel installation.
We can use /scripts/proxydomains to create DNS entries manually.

Resolutions
1)/var/cpanel/users/
/var/cpanel/users/username should have the following syntax per line “DNS=domain.com” line. If not, edit this file and change the line to DNS=domain.com

4)/etc/trueuserdomains

Packages not being displayed in Reseller WHM after transfer
Situation:
Sometimes packages will not be displayed in Reseller WHM >> Packages >> Edit, Delete lists after transfer.
The issue occurs when some packages are transferred with the accounts from dedicated servers, VPS etc to Shared/Reseller servers.
Solution:
1. Check if the packages are displayed under Create Account option in Reseller WHM.
2, If so check the package names : they should be prefixed with its owner name ‘user_’(Reseller account name).
3. If the username prefix is missing, it will not be available for editing or deleting in reseller WHM.
E.g: For a package ‘testpack’ under the reseller ‘new’.
The package name should be displayed as ‘new_testpack’.
4. If not, rename the package from the command line, prefixed with corresponding usernames.
mv /var/cpanel/packages/testpack /var/cpanel/packages/new_testpack
Then the package will become available for editing and deleting in Reseller WHM.
After this, all the accounts under the modified packages or plans should be updated with the new package name.
