Email processor types and requirements

With Legal Hold, you can use different email processor types. These types include:

Graph API email settings requirements
Gmail settings requirements
SMTP email settings requirements

Each type has its own setup that have different requirements.

Graph API email settings requirements

The Microsoft Graph API is an endpoint used to access data and services across Microsoft services. It is a RESTful web API that performs a variety of tasks. In this case, to send communications as a Microsoft user from Relativity.

When you use the Graph API as the email processor type in Legal Hold, you must add required credential information. First, collect the required Graph API email settings information. Then use the required information in the Adding email settings section.

Note: We recommend using the Graph API for email communications. When using the Graph API, you need to register your application in Microsoft Entra ID and set the permissions. For more information, see Using Microsoft Graph API for sending email communications.

SMTP email settings requirements

SMTP is a protocol for electronic mail transmission. The application or computer that sends, receives and relays email.

If you are intending to use Relativity Legal Hold, you need to add the required credential information below. First, collect the required SMTP email settings information. Then use the required information in the Adding email settings section.

Here are some reasons to use your own SMTP:

Legal Hold communications come from your trusted domain. An employee is more likely to interact with email from your domain.
Send communications from company's account. Using a different domain for the Send As results in emails getting flagged for spam.

Use the table below to gather the required information before proceeding to the steps.

Information label	Description of required information	Required information
User Name for SMTP	The username for the account on the SMTP server used for sending emails. This can be an email address or domain\username depending on the server settings. Even if your SMTP server is configured for anonymous authentication, you must input a value. For example, anonymous.
Password for SMTP	The password for the account on the SMTP server that Legal Hold uses for sending emails. Even if your SMTP server is configured for anonymous authentication, you must input a value. For example, anonymous.
Domain	The SMTP domain address. For example, smtp.office365.com.
SMTP Port	The SMTP port number. Note: We designed Legal hold outgoing emails to work with the SMTP protocol. This protocol runs on universally defined ports. We block most SMTP except 587. You must contact Relativity Support to open any other SMTP ports (25, 465, 587, 2525).
Use SSL for SMTP (Y or N)	The Secure Sockets Layer. Select Yes to use Secure Sockets Layer security for SMTP. You should consult with your IT department if you are unsure whether your SMTP server uses SSL.

Validating outgoing email settings

After configuring the Outgoing Email Settings, we recommend performing a system validation before Testing the outgoing email settings in the next section. The system validation process does not send an email. It simply confirms the outgoing settings and displays any errors if it finds them. For example, it will test for valid authentication method used, email server connection, email address, and mailbox, just to name a few.

To perform a system validation, click the Validate Outgoing button in the Settings console. If an error is discovered, a message displays with details so you can correct it.

Testing the outgoing email settings

After validating, you can proceed with confirming the settings were properly configured and ensuring the client's network accepts incoming emails correctly.

You will need the following to setup and test the email functionality:
