Smarsh uses SPF and DMARC technologies to ensure our mail can be successfully delivered and to prevent spoofing of smarsh.com as a sender.
We encourage you to implement these technologies and verify the legitimacy of all incoming email.
If you are using a third party spam filter with O365 this may at times cause a DMARC failure on our emails as the email inherits the spam filters source ip.
