Apple users can get an automatic configuration script that will sync any device’s default iOS or macOS mail app with the correct email settings.
To get this, log in to your cPanel account and navigate to Email Accounts. Next to your created email address, click Connect Devices. In this window, you’ll be able to see the configuration scripts on top of the page under Mail Client Automatic Configuration Scripts.
Next to iOS for iPhone/iPad/iPod and macOS® Mail.app®, click IMAP over SSL/TLS to prompt the file download.
After that, transfer the file to your apple device and just open it – this will open the default mail app. Input your password to connect your email.
