   • DNS Services – MX Records, CNAME Records Configuration Manger, AA Records, Dynamic IP etc.

   • Email Client Pre-requisites

3. Customizable Webmail Goals

   It is an Open Source Customizable Webmail Project mainly focussed on clients of organization that was mainly looking for the customizable web mail application which can also run webmail client and server on the low-end standalone servers for users in the basic browsers with the small set of the developer expectations. Well, the Customizable user base can be run on the intranet networking systems beyond the expectations of the customizable webmail developers. Webmail client is very much supportive and compatible with the smartphones outlook mail clients. In order to meet the developer needs at the extended needs of the customizable webmail client-base, the main principles of the customizable Webmail Projects which can be expanded into different customizable items.

   Customizable Webmail for Intranet is written in the PHP language and it is fully supports all the PC Web Browsers such as Mozilla Firefox and Internet Explorer etc. Developers can also deploy it on the dedicated Linux Web Server and in the Linux shared web hosting account. The webmail application is used integrate into the Control Panel of the shared local hosting web mail server which runs on the intranet.

5. How it Works?

   • After the installation and deployment of Customizable Webserver on the same system which it runs on the Intranet mail server, it also performs some of the basic logics and advanced configuration to know its configuration files, points the dns records of the configured files in the Customizable Web mail server with the advanced sql storage and the data storage.

   • It uses the advanced authentication system for authenticating the users on the intranet web mail server accounts for logging into the customizable webmail client. The same settings can also be configured on other email clients such as outlook, thunderbird and other email clients etc.

   • It also integrates the advanced feature of spam and email filtering can be set manually for the web mail user accounts. IP blocking and Email blocking feature is available to the webmail user whereas user can block the spam mails and suspected mails.

   • It also integrates with the advanced firewall for advanced security to the customizable web mail server where webmail users can enable or disable the custom ports and configure or allow the local IP addresses.

   • Performance

   • Performance of the Customizable Webmail is mainly depends on the tuning system of the PHP, webmail server and the MySQL Server. Which it doesn't cover the hardware tuning of the customizable webmail server.

   • It includes the tuning of network, tuning of file system, etc. Tuning should be performed in a regular schedule task by setting the tuning schedule points for auto-tuning.

   • Customizable Webmail application can be easily tested before or after making the changes under various mail server conditions which is important for developer.

   • For some of the developers it is more important that to make them to run faster them as fast as possible in the very large extent user base in the web mail server, the other applications may require to scale and tune the application to work well under the mail exchange base high-load conditions.

   • Even tuning can make the webmail application to run faster under the certain conditions or by using the particular hardware.

   • Tuning PHP for Webmail

   • By considering the PHP accelerators, it can speed up the webmail access by caching the data from webmail server in order to compile the PHP codes and it also optimizes the code. By eliminating the codes in the server to optimize it may need to do the recompile process the code for each and every single page load and multiple page loads.

   • This may probably require to do the easiest way in order improve the performance of the Customizable Webmail System.

   • By scheduling the auto tuning further it can improve the speed of mail exchange system and this can be carried out by some the accelerators.

   • PHP Acceleration for Webmail

   By enabling the PHP output compression for the customizable Webmail configuration. It doesn't require to enable the compression in the custom PHP configuation files (php.ini), it is because due to the certain scripts which don't work well with the customizable webmail which dont support some certain compressions and Customizable Webmail server can also take care of enabling and disabling the compressions according to the requirements and needs conditionally.

   It also keeps the include path of the custom defined setting information in the php.ini as it is very short as possible in order to optimize it with the help of most frequently used custom php mail library paths in the system.

   Developers don't need to include the path of the local or remote directory because Customizable Webmail System in the Intranet always uses the direct paths instead of using the relatively indirect paths for the directories of the webmail.
