Disable Phone Home Features

After successful deployment, you'll need to configure Mattermost for air-gapped operation. The following sections describe features that rely on internet access and offer recommendations for settings.

Mobile push notifications

Mattermost can use mobile push notifications to notify users of new messages and activity. These notifications require a server component to be deployed to send the notifications to mobile devices. By default, Mattermost uses the public push notification service, which isn't available in an air-gapped environment. We recommend disabling push notifications in System Console > Environment > Push Notification Server.

Email

Unless you've set up an internal air-gapped email service, we recommend disabling email invitations and email verification from System Console > Authentication > Signup.

Website link previews require a connection to the internet to fetch the content of the links. We recommend disabling website link previews in System Console > Site Configuration > Posts.

GIF picker

The GIF picker relies on a third-party service which has a dependency on external internet access. You can disable it in System Console > Integrations > GIF.

Notices

In-product notices require internet access to periodically inform administrators and end users of new product improvements, features, and releases. You can disable notices in System Console > Site Configuration > Notices.

Telemetry

To avoid log errors, we recommend disabling telemetry-related features, including the security update check, and error and diagnostics reporting features.
