CPanel Email Settings
Introduction
After creating an email account in cPanel, the next step is connecting it to an external mail client such as Outlook, Thunderbird, or a mobile mail app. To do this, you need to understand the core email protocols in cPanel: POP3, IMAP, and SMTP. In this article, we explain each protocol, when to use it, and how to find the correct settings in your control panel.
The Difference Between POP3, IMAP, and SMTP
1. IMAP (Internet Message Access Protocol)
Synchronizes messages directly with the server, so the same emails and folders appear on all your devices (computer, phone, tablet) simultaneously. Any action you take — deleting, archiving, marking as read — is instantly reflected across every device. Recommended for most users.
2. POP3 (Post Office Protocol)
Downloads messages from the server to a single device, and often removes them from the server afterward. This is suitable if you only ever access your email from one device and don’t need synchronization across multiple devices.
3. SMTP (Simple Mail Transfer Protocol)
This is the protocol responsible for sending messages, unlike IMAP and POP3 which handle receiving. Correct SMTP settings are essential to ensure your outgoing messages reach recipients without being flagged as spam.

How to Find Your Email Settings in cPanel
1. Log in to your cPanel dashboard.
2. Go to Email Accounts.
3. Next to the account you want, click Connect Devices or Set Up Mail Client.
4. All the settings you need will be displayed automatically, typically including:
- Incoming server addresses for both IMAP and POP3.
- Outgoing SMTP server address.
- Secure and non-secure port numbers.
- Username (your full email address).
Connecting Your Email to Outlook
1. Open Outlook and choose File > Add Account.
2. Enter your email address.
3. Select Manual Setup and choose the account type (IMAP is preferred).
4. Enter the incoming and outgoing server details as shown in cPanel.
5. Enter your username (full email address) and password, then click “Test Account Settings” to confirm everything works.
Common Email Setting Issues and How to Fix Them
- Errors when sending mail: Make sure you’re using the correct SMTP port (587 or 465) and that “My outgoing server requires authentication” is enabled.
- Old messages not appearing: Confirm you’re using IMAP rather than POP3, since POP3 may have already downloaded and removed messages from the server.
- Messages marked as spam by recipients: Check your domain’s SPF and DKIM records (covered in detail in our email security article).
