Remove noreply@salesforce.com or 'Sent on Behalf of' from Salesforce Outgoing Emails

Publish Date: Jun 11, 2026
Description
When the Enable Sender ID Compliance setting is turned on in Salesforce email deliverability settings, Salesforce automatically adds "no-reply@salesforce.com" to the Sender field of all outgoing emails sent from Salesforce.
Sender ID Compliance is an email authentication standard that verifies the sending server is authorized to send on behalf of the From domain. When enabled, it inserts a separate Sender address, which some email clients display as "Sent on behalf of."
This behavior occurs because the sending domain (salesforce.com) does not match the From domain (your organization's domain). Disabling the Enable Sender ID Compliance checkbox in Setup removes both the "noreply@salesforce.com" address and the "Sent on behalf of" phrase from outgoing emails.
Resolution

Use the following steps to disable Sender ID Compliance in Salesforce and remove "noreply@salesforce.com" or "Sent on behalf of" from your outgoing emails.

Salesforce Classic

  1. Click Setup | Email Administration | Deliverability.
  2. Locate the Email Security Compliance section.
  3. Deselect the Enable Sender ID compliance checkbox.
  4. Click Save.
  5. Emails you send no longer include "noreply@salesforce.com on behalf of..." in the Sender field.

Lightning Experience

  1. Click the gear icon and select Setup.
  2. In the Quick Find box on the left, type and select Deliverability, located under ADMINISTRATION | Email.
  3. Scroll down to the Email Security Compliance section.
  4. Deselect the Enable Sender ID compliance checkbox.
  5. Click Save.
  6. Emails you send no longer include "noreply@salesforce.com on behalf of..." in the Sender field.

For more information including required permissions, see the Salesforce help documentation on configuring email deliverability settings. If disabling Sender ID Compliance does not resolve the issue, contact Salesforce Support.
