SYMPTOMS
The File Format Application Programming Interface (FFAPI) access components SNADPUT.EXE and OSNADPUT.EXE, provided to 3rd party vendors, will return the following error code of 201 when the program is unable to successfully deliver a message to a postoffice.
CAUSE
The error is returned to the gateway when either SNADPUT.EXE or OSNADPUT.EXE are unable to insert the message into the postoffice database.
The 201 error code can be caused by one of the following conditions:
- Network file contention.
- Insufficient disk space on the postoffice database.
- Postoffice directory structure incomplete or corrupt.
- Insufficient access rights granted to gateway machine.
- Insufficient file handles.
- Network problems accessing the postoffice files.
- Corrupt or incorrect format of Microsoft Mail File Format (MMFF) file.
RESOLUTION
Network File Contention
SNADPUT.EXE or OSNADPUT.EXE must access certain files to create a message on a postoffice. Gateways that service postoffices that receive high volumes of message transfers and are serviced by the External program should consider using the mailer disabler (-md) parameter on the External command line or in the EXTERNAL.INI file.
The files accessed by SNADPUT.EXE or OSNADPUT.EXE with the -md option are: ACCESS.GLB, ACCESS2.GLB, MASTER.GLB, C850SORT.GLB, GROUP.GLB, NETWORK.GLB, CONTROL.GLB, INQUEUE3.KEY, and INQUEUE3.MBG.
The 201 error has been reproduced by locking the INQUEUE3.MBG file, and this may be the most common cause of the error. These files may be locked by other processes temporarily while in use. Postoffices located on Novell NetWare servers that operate under high traffic conditions should set the postoffice as shareable with few exceptions.
There are certain conditions that dictate that the CONTROL.GLB, TID.GLB, FLAG.GLB, and MASTER.GLB should only be accessed by one process at a time; thus, it should not be shareable.
For additional information, please see the following article in the Microsoft Knowledge Base:
99204 Doc Err: Setting Attributes for High Traffic Network
More information can also be found in the versions 3.2 and 3.5 Microsoft Mail for PC Networks "Administrator's Guide," page 25.
This problem can be compounded if the other External or Gateway is operating on a slow machine or over a slow link. The External option CompatV20 (-v20) will add additional file locking functionality. As a result, it increases the amount of network overhead and possibly causes additional network file contention. Additional network file contention can be created by improperly running the External program from a network drive (page 233 of the "Administrator's Guide").
Insufficient Disk Space
Insufficient disk space on the postoffice database will prevent the client from enlarging or creating postoffice files. Novell NetWare file servers can produce an insufficient disk space response to the program when the files have become ownerless or the purge file has used all available disk space.
Postoffice Directory Structure
The postoffice directory structure should consist of an initial 19 main subdirectories.
For additional information, please see the following article in the Microsoft Knowledge Base:
77926 Description of Mail Database Subdirectories
Insufficient Access Rights
The gateway components should be given full network access rights for the postoffice.

121798 Err Msg: You Do Not Have the Proper Access...
More information can also be found in the versions 3.2 and 3.5 Microsoft Mail for PC Networks "Administrator's Guide."
Insufficient File Handles
Increase the number of file handles to 50 in the CONFIG.SYS file of the MS-DOS workstation running the gateway.
Network Problems
The SNADPUT.EXE or OSNADPUT.EXE program utilizes the network to effectively perform the file commands that create and manipulate each file. Network problems that interfere with the operation of these commands can cause the above error to occur.
Microsoft Mail File Format (MMFF) file problems
Ensure that the MMFF file submitted by the gateway follows either the Basic or Extended Message Format for the SNADPUT.EXE or OSNADPUT.EXE program to properly convert (definition beginning on page 50 in the FFAPI SDK).
MORE INFORMATION
The error displayed may consist of three numbers separated by a hyphen (-) (201 - 1 - 140). The error code number 201 signifies that the error occurred when it attempts to insert the message into the database. The 1 can signify the number of messages sent per socket connection. The second number will rarely exceed 2. The last number refers to the line number of the message indicated by the second number. The last number is only valid if the problem was created by a corrupt or incorrectly formatted MMFF file.
