Before starting the setup process, ensure you have the following information at hand:

  • Email Address: The full email address you want to connect to (e.g., example@example.com).
  • Incoming Mail Server: The server that receives incoming emails, which can be an IP address or domain name (e.g., mail.example.com).
  • Outgoing Mail Server: The server that sends outgoing emails, also specified by an IP address or domain name.
  • Username: Your email account username (usually your full email address).
  • Password: The password associated with your email account.

Step 2: Launch your Email Client 

Open your preferred email client software on your computer, such as Microsoft Outlook, Mozilla Thunderbird, or Apple Mail.

Step 3: Add a New Email Account

  1. Locate the option to add a new email account within your email client. This option is typically found under the "Account Settings" or "Preferences" menu.
  2. Click on it to begin the setup process.

Step 4: Choose Account Type 

Select the appropriate account type for your email client software. For cPanel and DirectAdmin mailboxes, the most common options are IMAP or POP3. IMAP allows email synchronization across multiple devices, while POP3 downloads emails to a single device.

Step 5: Enter Your Account Information

  1. Your Name: Enter your full name or the name you wish to display as the sender.
  2. Email Address: Input your complete email address.
  3. Password: Provide the password associated with your email account.

  5. Outgoing Mail Server: Specify the outgoing mail server address given by your hosting provider or system administrator.
  6. Username: Input your email account username, usually your full email address.

Step 6: Configure Server Ports and Security 

Configure the server ports and security settings based on the recommendations below:

Incoming Mail Server (IMAP):

  • Port: 143 (unencrypted) or 993 (SSL/TLS encrypted)
  • Security: None (unencrypted) or SSL/TLS (encrypted)

Incoming Mail Server (POP3):

  • Port: 110 (unencrypted) or 995 (SSL/TLS encrypted)
  • Security: None (unencrypted) or SSL/TLS (encrypted)

Outgoing Mail Server (SMTP):

  • Port: 587 (unencrypted) or 465 (SSL/TLS encrypted)
  • Security: STARTTLS (unencrypted) or SSL/TLS (encrypted)

Step 7: Test the Connection 

To ensure the configuration is accurate, follow these steps:

  1. Click on the "Test Account Settings" or "Verify" button within your email client software.
  2. This test will verify the connection to your cPanel or DirectAdmin mailbox.
  3. If successful, you will see a confirmation message.

Step 8: Finish the Setup 

Upon successfully testing the connection, finalize the setup process:

  1. Click on the "Finish" or "Done" button within your email client software.
  2. Your email client should now be connected to your cPanel or DirectAdmin mailbox, allowing you to send and receive emails.

Conclusion: 

By following these steps, you can easily connect your email client to a cPanel or DirectAdmin mailbox. Remember to input the correct server details and ensure the port and security settings match the recommended configurations.
