ZTrust sends emails to users for various purposes, including user email verification, password resets, and server event notifications.&#x20;

To enable email functionality, you have to configure your SMTP server settings within ZTrust (under the Email tab)

#### **From**

#### **Host**

#### **Port**

It denotes the SMTP server Port.

#### **Encryption**

There are two encryption options available as outlined below:

* Enable SSL

This is a toggle button, when activated (turned ON), it enables [SSL](../../../../user-manual-ztrust-v2.0/key-terminologies#ssl) communication between ZTrust and its clients and applications.&#x20;

When deactivated (turned OFF), SSL is disabled.

You can toggle it ON or OFF according to your requirements.

* Enable StartTLS

This toggle button, when switched ON, activates [TLS](../../../../user-manual-ztrust-v2.0/key-terminologies#starttls) encryption for all data exchanges between ZTrust and its clients and applications.&#x20;

Conversely, when switched OFF, TLS encryption is disabled.&#x20;

You have the flexibility to toggle it ON or OFF  according to your specific needs.

You can choose the suitable options based on your preferences and needs.

#### **Authentication**

This toggle button is activated(turned ON) when your SMTP server necessitates authentication.

If authentication is not needed, it remains OFF.
