The information in this article applies to:

  • Microsoft Mail Gateway to SMTP, versions 2.1 and 3.0

SYMPTOMS

The Microsoft Mail Gateway to SMTP displays the following error message: 

   "ERROR MMFF protocol error
   NC_incoming: protocol error"
This error indicates that the SMTP Gateway program SMTPGET.EXE was unable to successfully build the Microsoft Mail File Format (MMFF) file. SMTPGET.EXE looks in the SMTP outgoing queue and creates the file SMTP\FROM_NC.API, which includes the message body and all attachments to be sent out to the SMTP host.

CAUSE

An incorrect MMFF file can occur if:

  • The original MAI file is 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

To correct this problem, delete or rename the SMTP\FROM_NC.API file on the gateway postoffice, then send the message again. If the error occurs frequently, check the server or network for possible problems.
