Summary: For any email user, it is crucial to have all their data under one roof. However, many organizations and individuals tend to keep their data in different EML files. Thus, for easier access and better flow of communication, it is important to move this data to a cloud-based email platform. Therefore, this blog will cover all the top methods to import EML to cPanel with all the attachments.

Client Case:

Our remote sales team uses various email clients; some use Thunderbird, others use Windows Mail. And they all save important customer interactions as EML files for record-keeping. Therefore, we are planning to centralize our email infrastructure on cPanel. Thus, we need a way for team members to upload their locally saved EML archives to the server. The problem is that cPanel’s webmail interface doesn’t natively support EML imports. Plus, our non-technical sales staff couldn’t handle complex IMAP configurations. We require a simple, user-friendly process to import EML to cPanel mailboxes.

Top-Rated Methods to Import EML to cPanel

This section will cover several reliable techniques to move EML files to cPanel. You can opt as per your technical expertise, volume of emails, and specific requirements.

01. Import EML to Roundcube with IMAP Email Client

As there is no direct way to import to cPanel, we will use Mozilla Thunderbird or Microsoft Outlook as a bridge. This will help to connect EML files and cPanel’s IMAP server.

  1. First, add a new account in your email client with your cPanel email address and password.
  2. Then, set the incoming server to IMAP with your cPanel server address (mail.yourdomain.com), port 993, SSL/TLS enabled.
  3. Next, create local folders to organize your EML files.
  4. Afterward, import EML files by dragging them into local folders or using import tools.
  5. Once imported, select emails from local folders (Ctrl+A to select all).
  6. Subsequently, drag and drop them into the corresponding IMAP folders to start uploading.
  7. During this process, keep the email client open and connected while synchronization completes.
  8. Finally, verify successful import by checking the cPanel webmail after completion.

Although this method is best for individual users. However, it is very time-consuming for batch conversion.

02. Transfer EML Files to cPanel Webmail With RoundCube Mail

Some cPanel webmail (Horde or RoundCube) interfaces support direct EML file uploads, though functionality varies by webmail application.

  1. Log in to your cPanel account (Horde or RoundCube) and open webmail.
  2. Step-1
  3. Then, select the folder (Custom folder) where you want to import your EML file
  4. Thereafter, right-click on the More option & choose Import.
  5. Step-2
  6. Next, use the file selector to choose the EML files from your computer.
  7. Finalize the process by clicking Import to transfer the files.
  8. STep-5

By following the above steps, you have imported your EML data to cPanel. This is a quick solution for a small import. However, this method only works with RoundCube & Horde webmail. Moreover, not all webmail clients support EML import. Plus, this method can be slow for multiple files.

03. Import EML to cPanel with Command-Line Tools

Users with Linux SSH access to their cPanel server can directly use the command line to inject EML files into mailboxes.

  • Firstly, access your cPanel server via SSH (Secure Shell).
  • After that, upload EML files to the server.
  • Thereafter, use Formail or similar utilities to process EML files.
  • Lastly, pipe emails directly into the mailbox directory.

With this, you can easily import EML to cPanel. However, this method requires SSH access and Linux knowledge. Plus, there is a risk of errors without proper expertise. Alongside, it is not suitable for shared hosting users & there is no graphical interface.
