I have a codeunit to make a notification email and send it through smtp. This CU is called from a batch job every evening, however it is hanging some nights.
I was wondering is there anyway to handle this error to just skip the email if it occurs:
The SMTP mail system returned the following error: (0x8004020F): The server rejected one or more recipient addresses. The server response was: 550 5.1.1 User unknown
