We experienced a temporary issue that caused some inbound (with semi-inline connection) messages to fail delivery, with senders receiving the following NDR: “This message could not be delivered due to a recipient error. Please try again later.” The issue has now been resolved, and email flow is back to normal. The system is up and running again, and the NDRs should no longer occur.
