Connect an email app

Use your mailbox provider's settings

Confirm whether the mailbox belongs to cPanel email, VerbumMail, or another service. Settings from one provider may not work with another. You need the complete mailbox address, its password, and the provider's server and encryption settings.

Find cPanel connection details

For a cPanel-hosted mailbox, open Email Accounts and choose Connect Devices or the equivalent mail-client setup action for that address. Use the secure manual settings shown for your account. Menu labels vary by cPanel version.

Enter the complete email address as the username when instructed. Use the hostname that matches the provider's certificate. Do not accept a certificate warning as a normal setup step.

Verify both directions

Send a message to an external account, then reply from that account. A successful incoming connection does not prove outgoing mail is configured. If authentication fails, confirm the mailbox password and username before changing DNS. If delivery fails, capture the error or bounce text without exposing the password.
