My company is sending promotion newsletter regularly via SMG. I'd like to compose a report about delivery failure and invalid recipient for the newsletter sender but I can't find a way to do so.
I tried to export audit logs in csv format, but to my surprise the delivery failures are not possible to be identified in the audit log csv format if there are multiple recipients in a single message.
I've found this article http://www.symantec.com/business/support/index?page=content&id=HOWTO53382 which may help:
Delivery failures are indicated with a Delivery Failure heading on the Audit Logs page in the Delivery section. In addition to being indicated on the Audit Logs page, undelivered messages are logged with the new DELIVERY_FAILURE audit log event. DELIVERY_FAILURE events are logged in the following format:utc|uid|DELIVERY_FAILURE|recipient|reason
