Use the connection details shown for your mailbox rather than guessing from another host’s guide. The correct hostname must match the mail server’s TLS certificate.
Configure the account
- Open Email Accounts and select Connect Devices or the available client-setup option.
- Record the secure incoming and outgoing settings and the required username format.
- Choose IMAP when you want messages synchronised across devices. Understand the retention implications before choosing POP.
- Enter the server names, ports and encryption modes exactly as provided. Enable outgoing authentication where required.
- Send a non-sensitive external test and confirm a reply arrives. Check Sent and other folders on each device.
If authentication fails
Confirm the full email address, current mailbox password and outgoing username. A cPanel login password may not be the mailbox password. Check whether a saved old password is being retried on another device.
Do not accept a certificate warning as a normal setup step. Ask support for the correct hostname. Avoid unencrypted connections on public networks, and protect devices with a screen lock. If a device is lost, arrange credential changes and session review promptly. Deleting an account from an app does not always delete its local downloaded data.
