I have been looking in the Application logs we are now recieving lots or errors saying a Non – delivery report with a status code 5.4.0 was gernatred for recipeint fpc822;[email protected]
Cause this messahe indicates a dns probelm or an IP address conf probelm.
We don’t have any email address where the people are trying to sent to? Can this be set not send out ndr reports? or stop the errors showing in application logs
