How to setup e-mail push notifications

How does it work?

When a chat user sends a message, it is first routed to the on-premises Ozeki Chat Server. From here, messages intended for desktop clients, such as Windows or Macbook users, are delivered through direct push notifications via UDP/IP. This protocol enables immediate message delivery across desktop platforms that are connected to the same network.

How do email push notifications work?

For mobile devices, including Android and iPhone, the server uses a different method. It sends email notifications through SMTP (Simple Mail Transfer Protocol). These notifications are transmitted over the mobile network as emails, notifying the user about the new message. This method allows for message delivery to mobile clients through email, which can be accessed even when the chat application is not actively running or if the user prefers to receive notifications via email.

In this setup, desktop and mobile devices receive notifications through distinct channels. Desktop clients receive notifications via UDP/IP, ensuring direct and immediate communication, while mobile clients are notified via email over SMTP. This structure allows for reliable message delivery across different types of devices. The use of email for mobile notifications ensures that users are alerted to new messages, even in scenarios where the chat application is not in use.
