Setup Mimecast as SMTP

---

An SMTP Server is an application that allows your device or server to receive and send Electronic Mails (e-mail) to various email receivers and senders. SMTP stands for Simple Mail Transfer Protocol and it is a standard for sending emails. They use a wireless carrier to route text/push messages to the inbox of email applications.

By default, miniOrange provides and uses its own SMTP Server to send OTPs to users. If you have a custom SMTP Server configured, you can use the same to send Emails from your miniOrange account. Check out our list of Supported SMTP Servers.

miniOrange IDP allows you to configure Mimecast as SMTP email provider hence giving you freedom to manage, monitor, and troubleshoot your email communications.

Prerequisites

• For Cloud Version - If your SMTP/Email servers are behind a firewall, make sure to open the right ports and allow inbound connections from our IP Addresses.

  You can whitelist the below IPs and open the given ports to make the request:

Region	IP
US	52.55.147.107
EU	13.51.230.230
AU	3.106.130.104
	54.206.97.196

• For On-Premise Version - If your SMTP/Email servers are behind a firewall, make sure to open the right ports and allow inbound connections from your server's IP Addresses.

Follow the guide below to configure a custom SMTP server in your account:

1. SMTP Configuration for Mimecast

• To configure an SMTP authentication, you must create a specific user account for sending mail (e.g., xyz@domain.com):
• Log on to the Administration Console in your Mimecast account.
• Navigate to Directories | Internal Directories. A list of your domains is displayed.
• Select a Domain. A list of the domain's users is displayed.
• Click on the New Address button.
• Complete the dialog as follows:
  • Enter the Email Address of the assigned account.

  Note: We recommend not using an administrator account because if the SMTP auth username and password are shared widely (e.g., among people configuring the printers), there could be issues.

  
  
  • Enter a Password for the account and make a note of it.

  Note: Cloud passwords must be used to allow SMTP / POP submiss ion. Ensure the default application setting has cloud password enabled. See the Managing User Email Addresses page for further information.

  
  
  • Enable the Password Never Expires setting.
  • In addition, enable the Allow SMTP Email Submission setting.
• Click on the Save button.
• Now, login to the miniOrange IDP dashboard with your miniOrange credentials and if you are using miniOrange On-Premise IdP, then login with your on-premise IDP credentials.
• Go to Customization -> Custom Email Provider and add the details which are available on the SMTP server side.





• Click on Save and follow the below steps to test the custom Email Provider.

2. Configuring the Device for SMTP

• Click on this link to get the Mimecast's IP Addresses for your region as the SMTP server.
• Use Port 587.
• Enable TLS Encryption.

Note: Mimecast does not support TLS 1.0 and TLS 1.1 as they have been deprecated since 25 March 2022. Instead, Mimecast supports TLS 1.2 and recommends that TLS 1.2 or TLS 1.3 be used in the end-user environment.



• Enable Authentication using the same login credentials (email address and password) configured in the above step.

3. Test SMTP

• Once the SMTP is set, you can enter a test email and click on Test Configuration to be able to verfy if the SMTP flow is working or not.
