Hi Craig, Using the criteria failure type "Hard" and Nature of failure
"Refused", there was no results. However, if we switch the query
resource to addressStatus and use the following criteria. We are able to
find some addresses that had the error text "email inbound bounce".Would
filtering the quarantined address by status "on denylist", error text
contains "inbound email bounce" and last delivery "" be an proper alternative? regards,Sengsiong
