 In cases where we can authenticate the sender, we use Sender Rewriting Scheme (SRS) to help the recipient email system know that the forwarded message is from a trusted source. You can read more about how that works and what you can do to help make sure the sending domain passes authentication in [Sender Rewriting Scheme (SRS) in Office 365](/office365/troubleshoot/antispam/sender-rewriting-scheme).
 
 For DKIM to work, make sure you enable DKIM for sending domain. For example, fabrikam.com is part of contoso.com and is defined in the accepted domains of the organization. If the message sender is [email protected], DKIM needs to be enabled for fabrikam.com. you can read on how to enable at [Use DKIM to validate outbound email sent from your custom domain](email-authentication-dkim-configure.md).
