SMTP: Err Msg: ERROR MMFF Protocol Error (100703)
The information in this article applies to:
- Microsoft Mail Gateway to SMTP 2.1
- Microsoft Mail Gateway to SMTP 3.0
This article was previously published under Q100703 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.
