Many personnel in the corporate environment choose to import MBOX file to cPanel email. Admins may use cPanel’s powerful features to develop and maintain their websites to perfection. 

If we look at the cPanel servers, we can see that they provide three different interfaces: Horde, Squirrel Mail, and Roundcube. These interfaces make it simple to manage and examine your email account. They also do so without first setting up their account. So, in this blog, we’ll show you how to import MBOX to cPanel email.

What is MBOX File Format?

An MBOX file is a standard email storage file format used by many open-source email clients such as Mozilla Thunderbird, Apple Mail, Eudora and many more. It stores emails in a single text-based file that contains email messages, attachments, metadata, and folder information.

As cPanel does not support MBOX import directly, there is a need for indirect solution.

How Does the cPanel Email System Work?

cPanel is a web-based control panel through which you can access emails of popular web based email clients. Such as;

  • Roundcube (most popular)
  • Horde (legacy support on some servers)
  • SquirrelMail (rare in recent setups)

Note: Older cPanel versions previously included Horde and SquirrelMail, but most current installations primarily support Roundcube Webmail.

IMAP is supported by cPanel email accounts that allows you to synchronise between your email clients and server storage. Thus, IMAP is a medium that supports to import MBOX files indirectly.
