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.

Microsoft Knowledge Base:

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.

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.

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).
