How to Set Up iOS Push Notifications

Valid for versions 88 through the latest version





This tutorial explains how to configure your WHM account so that users can receive push notifications for iOS® mail. We introduced this feature in cPanel & WHM version 64. When users enable push notifications, they receive notifications when new messages arrive.

You must export the Apple® Push Notification service (APNs) key, and then install the key on your WHM server to enable push notifications.

  • You cannot create APNs certificates in macOS Server® version 5.7.1 and later. The macOS® Mojave 10.14 operating system requires version 5.7.1 or later. For more information, read Apple’s macOS Server 5.7.1 upgrade documentation. You can request that Apple includes this feature in macOS Server 5.7.1 on Apple’s feedback forum.

  • You must open TCP outbound traffic for port 2195 if your firewall restricts this port. For more information, read our How to Configure Your Firewall for cPanel & WHM Services documentation.


Create, export, and install APNs keys on your macOS device.
