We are looking at using the .NET component to submit SMS messages but would like to be able to track messages that have failed to deliver.

We have set our account forwarding options to send "Status Report Emails" back to a central mailbox for message failed and message expired. This works fine except we would like to be able to identify the person in the status email who submitted the SMS.

Is this achievable??

We have looked at the custom email template format and can see a field called OriginalMessage_UserKey. Does anyone know what is contained in this field or how to set its value when submitting a SMS?

It would be possible to do this with the UserKey parameter.

When submitting message using the HTTP interface, you can add a 'userkey' parameter to the request. This value can be used for you own purpose, so could contain the name of the submitted.

Please note however, the UserKey parameter is not support by the .Net component.
