Apple Mail can manage a business email address hosted through cPanel. These steps use IMAP with SSL/TLS, which is the recommended option for accessing the same messages from your Mac, phone, and webmail.

Find the correct settings first

Before opening Mail, sign in to your hosting account’s cPanel and follow these steps:

1. Select Email Accounts.
2. Locate the email address you want to add.
3. Click Connect Devices.
4. Find the Secure SSL/TLS Settings (Recommended) section.
5. Record the incoming and outgoing mail hostnames, ports, and username shown there.

Use the server names supplied by your hosting provider. The correct hostname might be your domain’s mail hostname or the hosting server’s name. It needs to match the certificate used by the server.

Add the account in Apple Mail

1. Open Mail on your Mac.
2. Choose Mail > Add Account.
3. Select the option to add another mail account, if your hosted email provider is not listed.
4. Enter your name, full email address, and mailbox password.
5. Continue through the prompts. If Mail cannot configure the account automatically, enter the details manually.
6. Select IMAP as the account type.
7. Enter the incoming mail hostname from cPanel, your full email address as the username, and your mailbox password.
8. Enter the outgoing SMTP hostname from cPanel, again using your full email address and mailbox password.
9. Finish the setup and allow Mail to synchronize the mailbox.

Check secure server settings

Open Mail > Settings > Accounts, choose the account, and click Server Settings. If Mail is managing connections automatically and the account works securely, you can leave those settings in place.

If manual settings are necessary, turn off Automatically manage connection settings and enter the settings supplied by your provider:

Service	Recommended configuration
IMAP incoming	Port 993, Use TLS/SSL on
SMTP outgoing	Port 465 with SSL/TLS or 587 with STARTTLS, according to the provider
Username	Your full email address
Authentication	Provider-approved mailbox credentials

The outgoing server list can be found in Mail > Settings > Accounts > Server Settings > Edit SMTP Server List.

Never disable encryption or approve a certificate mismatch just to finish setup. If a hostname produces a certificate warning, confirm the correct hostname with your provider.

Test and troubleshoot

Send an email from the Mac to another address, reply to it, and confirm both incoming and outgoing mail work. Check the same account in webmail to make sure messages are synchronizing.

If incoming email works but sending fails, check SMTP authentication, the outgoing server name, the selected port, and the mailbox password. If both directions fail, confirm that the account exists and is accessible through webmail.

Removing an account from Apple Mail can remove locally stored messages from the Mac. Review any locally stored mail before deleting and recreating the account.
