How to hide Salesforce email address?

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.
