PC Ext: Err Msg: Error 021: Message Was Not Delivered...
ID: Q103960
|
The information in this article applies to:
-
Microsoft Mail for PC Networks, versions 3.0, 3.2
SYMPTOMS
If there are several mail transfer agents (MTAs) on a hub postoffice
and some of the MTAs have the -V20 command-line parameter enabled,
Microsoft Mail users may receive messages returned from the Postmaster
with the following error message:
Error: [021]
Message was not delivered due to missing routing file.
This message will also appear in the SYSTEM.LOG file, and the
following corresponding errors will appear in the SESSION.LOG file:
opening FIPS file. Failure to open file
File I/O: Error opening "M:KEY\INQUEUE3.KEY" error code=32
File I/O: Error opening "K:P1\0000000E.0LK", error code=2
File I/O: Error finding "M:MAI\MAE\0009DF5E.MAI", error code=2
CAUSE
There are two causes of this error:
- The mail is delivered--the MTA is able to read the P1 file in
memory; however, after delivery the MTA failed to delete the P1
file and declares it missing. Therefore, users see mail being
delivered, but they still receive the original error.
- The P1 file really is missing when the MTA tries to read it into
memory.
This error only occurs when multiple MTAs are processing a single
INQUEUE3.MBG file. In Mail version 3.0, if the INQUEUE3.KEY file gets
locked open, the MTA will not handle the open failure properly;
therefore, the MTA cannot delete the mail item. However, it does
successfully delete the P1 file.
STATUS
Microsoft has confirmed this to be a problem in version 3.0 of
Microsoft Mail for PC Networks. This problem was corrected in version
3.2.
MORE INFORMATION
This error may occur in Mail version 3.2 if SOME External Mail
programs or gateways have the CompatV20 (V20) option enabled. The
solution is to be consistent with how this option is implemented on
each hub postoffice: the option should be set to All or None.
Having -V20 on some of the Externals will force those Externals to
lock the INQUEUE.KEY file differently. The following is an analysis of
having three Externals without, one PROFS 2.1g gateway without, and
one External with the -V20 option, all of which process mail on a
single hub postoffice.
- The External Mail program creates the INQUEUE.OLK file, opens it
RDWRT|DENY_ALL, and processes Inqueue.
- The PROFS gateway locks Inqueue with READ | DENY_READ and starts
processing mail time (oblivious to INQUEUE.OLK)
- The PROFS gateway may outpace External, deliver its mail, and
delete its .MAI and .P1 files.
- External delivers the mail, but is unable to delete the .P1 files
properly. (It misses the window and cannot find the .P1 and/or .MAI
files the gateway just delivered. External will log that it is
unable to open or find the FIPS file when trying to deliver mail).
It is also possible for both the External and the gateway to
successfully process the .MAI and .P1 files (in this scenario, the
users could get duplicate mail).
