Very infrequently an error message can be thrown in association to a send: ExactTarget.OMM.OMMWarningException: An error occurred when attempting to send the subscriber email to the MTA. Only one of these errors will be logged per batch. The MTA connection is being reset and the injection will be retried.

Sends can fail or be temporarily delayed due to this behavior.

1. Send a significant amount of email
2. Intermittently encounter this

Retry sending/restart sends.
