How to Setup Email Relay in Salesforce - Learn Here

In this blog, we got to know How to setup Email Relay in Salesforce.

Reviewing the Current Setup of our Salesforce ORG

Login in your Salesforce org.
Open the record from which you want to send the email.
Click the Activity tab and then click Email.
Send an email to your desired mail id.
Open your mail and check. (If you did not receive it at your primary, then check your spam box.)
After opening that email, you will notice a random string generated by the salesforce itself at the sender’s address.
Example:- zeso3f4y6ruv7w4.uxim1.5j-34pqleam.ap27.bnc.salesforce.com
This only tells us that right now our emails have been sent from the Salesforce SMTP.

In the search bar we need to type SMTP Relay and click on SMTP relay service.

On Hovering the mouse on SMTP relay, it will pop up the configure button, click on the button.

At allowed senders you can give three types of permission i.e.
- Only Registered App users in my domains- The sender must be a registered user in one of your domains.
- Only Addresses in my domain-The sender doesn’t have to be recognized as a G suite user, but must be in one of your registered domains. This can be useful when you have a third party or custom application that needs to send messages.
- Any Addresses (not recommended)- The sender addresses can be anything, even outside of your domain.

We will be choosing the only address in my domain as the Salesforce send IP ranges to accept our SMTP server.

Click on ‘Add IP Range’ here we have to add all the IP range one by one, to get your own range of IP address please refer to this Document Salesforce IP Addresses and Domains to Allow and click save.

Leave SMTP authentication unchecked in this case Google enforces the uses of SMTP authentication to identify the sending domain.

Check the box ‘Require TLS encryption’ for communication between your server and google ‘s server it encrypts even your message.
