Sophos Central Email Relay Options

Hello,

An external service should be able to relay via Sophos Central. The IP address has already been added under "Address/Domain/IP address".
Unfortunately, we receive the error message "554 5.7.1 : Recipient address rejected: Access denied". Which settings must be changed so that the IP address is allowed to relay via Sophos Central?
