Cause
Exchange server is set to X message rate limit. This means that the Exchange server can only send X emails concurrently. When a large number of emails that exceed the limit go through the mail server, it will fail due to the limitation.
Resolution
Change the receive connector MessageRateLimit from X to 20 or 100, depending on your mail load. From Exchange Server Support forum; 421 4.4.2 Message submission rate for this client has exceeded the configured limit.
