by Notification: Outbound Mail Failure
MSEXCH:IMS:::MAIL 0x80070057 (00050311) Conversion to Internet format failed
Event Log
An error was returned from the messaging software the Internet Mail Service
uses to process messages on the Microsoft Exchange Server. It is possible
that the piece of mail being processed at the time will be returned to the
sender as a failed delivery instead of being delivered. The message will be
moved to the "BAD" folder, if possible, and the error is not a temporary
error. Otherwise it will be retried when the service is restarted. Use the
appropriate utilities found in the SUPPORT directory of your Exchange CD to
view and manipulate messages that have been moved to the "BAD" folder.
