This message usually indicates an issue on the receiving server.
If delivery fails after multiple attempts, an NDR with a permanent failure code is generated. Transient network conditions or a server that is experiencing problems can cause this error.
The sending server will retry to deliver the message for a specific time period, and then it will generate further status reports.
Monitor the situation as the server retries delivery.
This might be a transient problem that might correct itself.
This situation can also occur when the message size limit for the connection is reached, or if the message submission rate for the client IP address has exceeded the configured limit. The sending server tried to relay or deliver the message, but the action was not completed before the message expiration time occurred.
