Configure SMTP Gateway

An SMTP Gateway, also known as an SMTP relay, is a service or server that acts as an intermediary between email clients and email servers to facilitate the delivery of emails. When a user sends an email from their email client, the email is first sent to the SMTP Gateway. The SMTP Gateway then processes the email and forwards it to the recipient's email server. The recipient's email server then delivers the email to the recipient's inbox.

SMTP API Gateway is a service that provides an API interface to interact with SMTP Gateway functionality. It allows developers to integrate SMTP Gateway functionality into their applications to send Email.

User Persona: App Administrator

On configuring SMTP the App Administrator can test if it can successfully send mail. Let’s explore more on SMTP configuration and testing.

4. Select and Enter the appropriate details in the required fields. Refer to the following sections about the configuration details.

   • General

   • Primary and Secondary Gateways

     Gateways and its Dependency on the Platform Components

     The system provides two types of SMTP gateways namely:

     Relay

     API

     Multiple Primary and Secondary gateways can be configured for different Domains, OUs & Tenants, and also for the Global level. However, the following rules apply:

     • A Global level has only one Primary & Secondary gateway.
       

     • Each Tenant can have only one Primary and Secondary gateway.
       

     • Each Sub Domain can have one or more Primary and Secondary gateways.

       Example: Sub Domain with a combination of the following Tenants can have multiple primary and secondary gateways.

       HR and IT can have a Primary and Secondary gateway.

       IT and Finance can have a Primary & Secondary gateway.
       

     • Each Domain can have one or more Primary & Secondary gateways based on different combinations.
       

     • If any two combinations are similar, then the second similar combination becomes invalid.

General

This section allows to configuration of SMTP at the platform levels such as Global, Domain, Sub Domain, and Tenant.

Primary and Secondary Gateways

The SMTP Type field will be shown in both Primary and Secondary gateways.

Note

The primary gateway is a mandatory configuration for any level of gateway settings. Based on the selected SMTP type the configuration screen is displayed.

The following SMTP types are available in the dropdown list.

• Relay

• API

The maximum number of SMTP scenarios are as follows:

Relay

SMTP Relay is a process of sending emails through a SMTP server. SMTP servers are often used as relays because they can handle large volumes of emails, and ensure that emails are delivered to their intended recipients.

To configure Relay Type, perform the following steps:

1. Select Relay as SMTP Type to send email through the SMTP Server.

   

   Figure: Relay SMTP
   

2. Enter appropriate details in the required fields.
   
   The following table provides details regarding Field Description.

   Submit	Click Submit, to save the SMTP configuration and view it on the List page.
   Cancel	Click Cancel, to exit from the configuration.

API

API (Application Programming Interface) is a set of protocols, tools, and standards for building software applications. An API allows different software applications to communicate with each other. When the SMTP Type selected is API, then the configuration fields related to the API type are displayed.

To configure API Type, perform the following steps:

1. Select API as SMTP Type, to send email through the application interface.
