Cause of the Problem

An incorrect MMFF document can occur if:
  • The original MAI document was corrupt.
  • A problem occurred on the Mail Postoffice server during the SMTPGET process.
  • A problem occurred on the network between the SMTP gateway computer and the Mail Postoffice server as SMTPGET.EXE was trying to execute.

Resolution method 1

To correct the problem, remove or rename the SMTP\FROM_NC.Application Programming Interface document on the gateway postoffice, then send the symptoms again. If the unrecoverable error occurs frequently, check the server or network for possible problems.
