Hii Himanshu,
According to your question that I understood is that you want to remove the email address which looks like something like this “noreply@salesforce.com on behalf of”. So to remove this follow the below steps:-
- Click on Setup | Email Administration | Deliverability.
- Locate the Email Security Compliance section.
- Unselect the Enable Sender ID compliance box.
- And then Click Save.
The emails you send will no longer include the “noreply@salesforce.com on behalf of”.
Thanks.
