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?

the ip address which should relay via sophos central was added here
