A free and open source webmail interface, Roundcube makes it easy for users to configure their cPanel email accounts. It boasts of desktop-like features that you can take advantage of with your cPanel account. Best of all, it comes with all sorts of customizations that will make your webmail all the more enjoyable to use.
Important Pre-Customization Notes
When you customize your Roundcube interface, you will gain complete control and access over the experience of the end user. Keep in mind though that you cannot do perform these customizations via cPanel, so you have to do it through your Roundcube account itself. However, you can perform the customization of the Roundcube installation via cPanel.
Your Configuration and Customization Options
One of the best things about Roundcube that makes it one of the most preferred webmail interfaces is its more than 200 configuration options. These provide users the ability to customize their webmail depending on their particular tastes and requirements. Once you have installed the interface, you have to create and adjust the local configuration files.
Minimal Setup Customization Options
Below you will find just a few of the customization options for database connections and IMAP connections. You need to perform these prior to using Roundcube.
For Database Connections
This serves as the database connection string for tasks involving read+write operations. The format looks like this: “db_provider://user:password@host/database “(without the quotation marks).
It currently supports db_providers: mssql, mysql, sqlite, pgsql, and sqlsrv.
For those using SQLite, make sure you use the absolute path, which is: “sqlite:////full/path/to/sqlite.db?mode=0646” (remove the quotation marks).
This key encrypts the IMAP passwords of users temporarily saved in their session database. Do not use the default value for your own security; always use the Roundcube installation encryption key.
For IMAP Server Connections
In default mode, the log in page for Roundcube displays a text box where you have to put in the value of the IMAP host will connect to. You can hide this text box by setting this fixed IMAP host address: “$config[‘default_host’] = ‘localhost’;” (do not include the quotation marks).
Using any of these prefix together with your hostname will allow you to use either the SSL or the TLS connection.
In many cases, you do not have to worry about logging in email accounts with case-sensitivity in mind. And by default, Roundcube automatically converts usernames keyed in the login form into lower case. However, when you have an IMAP server that has case-sensitivity features, you can use ‘login_lc’ to configure Roundcube’s conversion method when entering usernames during login processes.
Use the value 0 to disable the conversion, the value 1 for converting only the domain part of the email, and the value 2 (the default) for converting everything into lower case.
You can use this key when you have an IMAP server that does not provide support for UTF-8 for passwords.
This key automatically adds the domain to all the usernames for login purposes. However, you only require this for IMAP servers needing the entire email address (including the domain, for example, mydomain.com) during logging in.
There are plenty of other ways to customize your Roundcube interface, but you can start with these ones.
