The process in a Nutshell
Integrating Custom Webmail Applications in cPanel’s Webmail interface involves the following simple and efficient steps:
- The first step is creating the Webmail Application’s Registration File.
- The next step is Placing and Modifying the Application
- The final step is Packaging the Webmail Application to successfully complete the process.
A Detailed Development
The above-mentioned process of integrating custom webmail applications can be efficiently carried out as follows:
1) Creating the Registration File – It is a YAML file with one hash which requires a URL, a Displayname and an Icon.
- While the URL is the the path to the webmail application, the icon is the path to the icon displayed by the cPanel interface and the displayname the name which the cPanel interface will display.
- Once the system has generated this file the Webmail Application will appear in the cPanel interface.
2) Placing and Modifying the Application – This step involves placing the actual webmail application file in the cPanel/respective directory as the system executes applications within that directory.
- The file having been placed in the directory, a few necessary modifications must be made to file so as to ensure its efficient operation in the cPanel interface.
- Automation of Logins – To do this one must modify the login form so as to access or pull the authentication data from REMOTE_USER and REMOTE_PASSWORD environment variables and then, place the authentication data in hidden form fields that are located within the login page.
- Editing the Configuration File – This involves editing a few key settings such as the specification of User Files storage path, the System Application Paths, the Mail Server to be used and the name and credentials of Databases to be activated.
- Configuring the Database – It is essential to separate the databases for Webmail Applications so as to prevent the generation of shared passwords between cPanel accounts.
This can be done by storing the databases on the user’s directory using SQLite if it is compatible with the application.
3) Packaging the File – Once the webmail application has been integrated, it has to be packaged or made ready for installation.
- To do this one should package the file in a .tar format with pristine sources and a patch included, as well as installation and uninstallation scripts.
- The pristine sources and patch allow users to see the process through which the integration of the application was achieved and the modifications made to the source file.
- The installation and uninstallation scripts simply smoothen and effect the application’s installation process for the user.
Once all of these aforementioned steps have been followed and successfully executed, the Integration of the Custom Webmail Application is complete.
