Configuring an Email Client

An email account created in cPanel can be added to an email application such as:

  • Microsoft Outlook,
  • Mozilla Thunderbird,
  • Apple Mail,
  • a mail app on your phone,
  • another application that supports IMAP/SMTP.

The safest option is to use the SSL/TLS settings shown directly in cPanel.

1. Where to find the configuration details

Log in to cPanel and go to:

Email → Email Accounts

Find the mailbox you want to configure, for example:

kontakt@domena.pl

Then click:

Connect Devices

This section shows the exact settings required to configure your email client.

You will find information such as:

Username
Password
Incoming Server
Outgoing Server
IMAP Port
POP3 Port
SMTP Port

Use the details shown in your own cPanel. The server name may be different for different hosting accounts.

2. IMAP or POP3

For normal email use, we recommend:

IMAP

IMAP synchronizes messages with the server.

This means you can use:

Outlook
phone
Webmail

at the same time and see the same messages and folders everywhere.

POP3 is mainly used to download mail to a device and is not the best choice in most cases.

3. Typical IMAP settings

For a secure SSL/TLS connection, the most commonly used settings are:

Account type: IMAP
IMAP port: 993
Encryption: SSL/TLS

Read the incoming mail server name from:

Email → Email Accounts → Connect Devices

4. Outgoing mail settings — SMTP

SMTP is used to send messages.

For an SSL/TLS connection, cPanel typically provides:

SMTP port: 465
Encryption: SSL/TLS
SMTP authentication: required

Use the full email address as the username:

kontakt@domena.pl

The password is the same as the mailbox password.

5. Example configuration

Example:

Email address:
kontakt@domena.pl

Username:
kontakt@domena.pl

Password:
mailbox password

Incoming mail:
IMAP

IMAP server:
name shown in Connect Devices

IMAP port:
993

Encryption:
SSL/TLS

SMTP server:
name shown in Connect Devices

SMTP port:
465

Encryption:
SSL/TLS

SMTP authentication:
Yes

Do not copy an example server name from another guide. Always check it in your own cPanel.

6. Configuration in Microsoft Outlook

When adding the account:

  1. Open Outlook.
  2. Select the option to add a new account.
  3. Enter the full email address:
kontakt@domena.pl
  1. If Outlook does not configure the account automatically, select manual configuration.
  2. Select:

IMAP

  1. Enter the settings from:

cPanel → Email → Email Accounts → Connect Devices

  1. Enter the mailbox password.
  2. Save the configuration.

7. Configuration in Mozilla Thunderbird

  1. Open Thunderbird.
  2. Select the option to add an existing email account.
  3. Enter:
name
email address
password
  1. If Thunderbird does not detect the settings automatically, select manual configuration.
  2. Set:
IMAP
SSL/TLS
port 993
  1. For SMTP, use the settings shown by cPanel.
  2. Save the configuration.

8. Configuration on a phone

When adding the account, select:

Other

or:

IMAP

Then enter:

email address
password
IMAP server
IMAP port
SMTP server
SMTP port

You can find the exact server names in:

Email → Email Accounts → Connect Devices

9. Email login

A very common mistake is using only the mailbox name.

Do not use:

kontakt

Use the full address:

kontakt@domena.pl

This applies to:

  • IMAP,
  • SMTP,
  • POP3.

10. Incoming mail works, but sending does not

If you can receive messages but cannot send them, check the SMTP settings.

The most common causes are:

  • incorrect SMTP port,
  • missing SSL/TLS encryption,
  • SMTP authentication disabled,
  • incorrect username,
  • incorrect password.

The SMTP settings should match the information in:

Connect Devices

11. After changing the password

If you change the mailbox password in cPanel, you must also update it on all devices and applications using that account.

Example:

Outlook
phone
tablet
Thunderbird

The old password will stop working.

12. Simplest procedure

To configure email:

  1. Log in to cPanel.
  2. Go to:

Email → Email Accounts

  1. Next to your mailbox, click:

Connect Devices

  1. Read the SSL/TLS settings.
  2. In your email client, select IMAP.
  3. Enter the full email address as the username.
  4. Enter the IMAP and SMTP settings shown in cPanel.
  5. Enter the mailbox password.
  6. Save the configuration.
  7. Send a test message.

Done.
