Hi James,
How was the file you are attempting to resend created? Is it a saved message file or was it saved via the resend function in SMAT? SMAT will only open up valid saved message files (consisting of an idx and msg file) . If the file was created using the Smat resend function, the file format is len encoded not new line.
You also need to know if the messages you are attempting to resend were previously processed by your pre-tps outbound proc. If so, normally you would not want to run them through again.
