Must all sender addresses of outbound e-mail be real e-mail addresses?

By March 25, 2019August 11th, 2020FAQs

If your company uses e-mail address not linked to a user such as [email protected], there is an “Unknown Sender Address” setting under the Web Interface > System > Outbound Control tab. By default it is set to “Reject Message”. If it is set to “Allow Message”, the Sendio ESP will accept outbound e-mail from unknown senders such as [email protected]. For more information, please refer to the Administration Manual.
