Microsoft Mail for PC Networks, version 3.2
SUMMARY
Version 3.2 of Microsoft Mail for PC Networks contains the following
enhancements and corrections:
SERVER ENHANCEMENTS
- Multitasking Message Transfer Agent (MTA), which is sold separately.
- Microsoft Windows Move User utility that can move users from version
2.1, 3.0, and 3.2 postoffices to version 3.0 or 3.2 postoffices.
- Two different Batch User Create utilities that can create new users
on a local postoffice. One reads the Novell NetWare 2.1x or 3.11
bindery, the other reads the NET.ACC file from a Microsoft LAN
Manager user level security file server.
- Microsoft Mail Gateway to AT&T Easylink Mail (U.S. product only).
- Transfer mail through native X.25.
- Ability to limit message size when transferring over a network.
- MTA can be configured to reboot automatically if critical error
is detected.
- Postoffice is no longer limited to one Dynamic Drive table.
- Mail is now transferred by the MTA using First In/First Out (FIFO).
- Improved reliability of the asynchronous transmission protocol.
- Improved algorithm for handling P1 files.
- Improved error messages in SYSTEM.LOG.
- MS-DOS MTA low memory conditions have been improved. Also, more
reliable with large message bodies.
- OS/2 Rebuild runs 35% to 55% faster than MS-DOS Rebuild.
- Directory Synchronization (DirSync) does not update any of the
GAL files if any of them are in use.
- The Administrator program updates versions 1.0 and 1.0a of Microsoft
Schedule+ for Windows calendar (.CAL) passwords.
SERVER CORRECTIONS
Bug # Description
------------------------------------------------------------------------
7 IMPORT -A causes an incorrect mailbag assigned when importing
SNADS, PROFS, and OfficeVision addresses.
Version 3.0 of Import creates a separate mailbag for each
SNADS, PROFS, and OfficeVision user instead of pointing all
imported users to the mailbag for their gateway. Since the
gateways only check the gateway mailbag, the mail messages
never get delivered.
60 External does not report an error on a lost .MAI file.
A new error message will be received by the sender when the
version 3.2 of External cannot find a .MAI file. The error
that the user sees is:
"Message was not sent due to missing message file"
It will also be logged in the SYSTEM.LOG with the error
message:
"Mail retry count exceeded sending to: username error."
61 External reports incorrect error sending mail with lost
.ATT files.
If a mail message is created with attachments and saved to be
sent later using the MS-DOS client, but before the message is
sent one of the attachment files gets deleted. Then version
3.0 of External will report various errors in SYSTEM.LOG and
SESSION.LOG.
Version 3.2 of External will report a non-delivery message to
the sender:
"Mail was not sent due to missing attachment."
There will also be an accompanying notice in the SYSTEM.LOG.
62 Infinite "disk error" when out of disk space sending
attachment.
When version 3.0 of External tries to send a message with an
attachment to a postoffice with insufficient disk space, then
external tries to send this message indefinitely (or until the
lifespan of the message is exceeded).
In version 3.2 of External, before each mail item is sent the
destination PO drive is checked for available disk space. If
not, the drive will be marked as FULL and delivery will be
attempted at the next interval update.
64 External: Locked files cause incorrect delivery.
Version 3.2 of External now puts an error message in
SYSTEM.LOG.
65 External loses messages under low memory conditions.
Version 3.2 of External now properly returns undeliverable
messages by only parsing the data necessary to return to
sender.
66 External: Postoffice not processed if mailbag is missing.
In version 3.2 of External, if the mailbag for a particular
postoffice is missing, External will log the error,
"Drive in error: M:"
to the screen and SESSION.LOG. It will continue to process
mail on this drive to other locations.
68 External ignores Admin settings for baud rate.
In version 3.2 of Admin, the baud rate setting for external
postoffice definitions has been removed. The following
reasons support this decission:
- It is ignored in older versions
- Incoming call rates are not predictable
- Modem scripts over-ride the default
69 External does not deliver large messages.
Version 3.2 returns these messages to sender with an
explanation.
71 Admin: Adding SNADS user without adding DGN gets wrong
address.
When adding a SNADS user to the postoffice address list with
Admin, if the DGN for that user was not already defined, Admin
created the wrong address for the user and mapped the name to
an existing DGN even though the administrator correctly typed
in a valid DGN in the DEN.DGN. This address which is added to
the postoffice address list is correct, but the added reference
to gateway list for this DGN/NODE was incorrect.
This was also a potential problem for PROFS/OfficeVision users
when adding users to NODES not already defined. The correct
behavior is to not add the user and the reference to the
gateway list when DGN/Node is not already defined.
72 External: Multiple modem messages put in response buffer.
Version 3.0 of External would occassionally get the error:
"failure to initialize modem"
upon initializing the modem. External was incorrectly reading
the modems' response buffer.
76 Import accepts transaction without mailbox name.
Version 3.2 of Import will not create a user account unless a
valid address exists in the import file. Version 3.0 of Import
would let you add a user even if you forgot to include the 10
charactor mailbox name.
82 Admin: Remote client cannot read external POs and gateways
listed in RNETWORK.GLB file.
When regenerating the directory view for Remote clients, the
Admin utility would corrupt the RNETWORK.GLB file if there
were no additional external Postoffices defined within the
same Network.
179 DirSync updates lost in import request.
In version 3.2, the SRVSEQ value (the # of the last
transaction sent to this Requestor) used as a reference to
the local directory store is now read from the Server PO
REQCONF.GLB and not from SRVCONF.GLB. This will keep track
of Import requests properly.
329 Import does not handle FFAPI add transactions properly.
Version 3.2 of Import will now treat FFAPI type addresses
the same as PCM type addresses.
370 Reqmain: No message sent to Admin if REQTRANS.GLB is not
processed.
Version 3.0 would not report an error if REQTRANS.GLB was
corrupt. Version 3.2 will report:
"FATAL [ 40] Possible database corruption detected:
REQTRANS."
371 Srvmain: No message sent to Admin if MSTTRANS.GLB is
corrupt.
Version 3.0 would report no error if the MSTTRANS.GLB is
corrupt. Version 3.2 reports a fatal error that is sent to
the Server Administrator as part of the summary report for
DirSync.
680 External: Circular routing problems.
Version 3.0 of External can cause circular routing of
messages when more than one External is sending mail from
the same postoffice at the same time.
1149 Attachments can be stranded if external connection is
dropped.
Version 3.2 of External will now stop the delivery of a
message if the transport layer fails while delivering
attachments.
1314 Attachments not always deleted from postoffice.
In version 3.0, the attachment delete loop would cause
only the first attachment of a message to be deleted when a
message was deleted.
1361 External: X.CSI wastes too much time recovering from Return
No Response (RNR) and Reject (REJ).
Version 3.2 of External will rely on modem hardware flow
control (RTS/CTS) in the SIO layer when RNR or REJ's occur.
Version 3.0 External would idle for 10 seconds per each RNR
or REJ's, causing unwanted timeout problems.
1362 External: X.CSI finding the start of a packet is slow.
Version 3.0 External called a DosRead() for every byte from
the COM driver buffer when searching for a STX character. At
high speeds this meant hundreds of 1 byte DosReads() creating
high CPU usage. Version 3.2 of External now reads in multiple
bytes into a special STX buffer greatly reducing CPU demand.
1365 External: X.CSI dumping bad packet can cause problems.
Version 3.0 of External will copy data from the protocol ring
buffers (X.CSI) to the SIO layer if X.CSI becomes full.
Version 3.2 External will not.
In version 3.0 of External, the CRC calculation on a data
packet is performed after the data is read from SIO,
therefore, it is redundant to dump the data back to the SIO
layer because it already resides in a X.CSI window packet
buffer. Version 3.2 of External will now drop these packets
and retain optimal performance.
1420 External: Machine hangs with low disk space and expired
useful life.
Version 3.0 of External will hang upon delivering an "expired
useful life message" on a PO that does not have enough
diskspace. Version 3.2 of External resolves this issue by
logging the low diskspace and not attempting to deliver mail
to that PO until space is available.
1645 Srvmain does not update ReqSync when DirSync .ATT is
corrupted.
If a corrupted DirSync attachment is processed by version 3.0
of SRVMAIN, it will add transactions to the queue up to the
point of corruption and then terminate. However, it does not
update the ReqSync field in the SRVCONF.GLB file to indicate
that some transactions were processed/received. No
transactions will be lost in this scenario, but duplicate
transactions will be submitted by the requestor.
Version 3.2 of SRVMAIN resolves this by taking the Reqsync
number directly from the last record processed in the
SRVCONF.GLB file instead of from the mail text body. If there
is a CRC read error in the transaction file, all records up to
the corrupted one will be processed.
1646 External: Duplicate mail incident.
When mail is composed to multiple recipients, version 3.0 of
External would lock the mailbags for the externally defined
postoffices before the Dispatch process started. The mailbag
was not locked while External was collecting mail. Therefore,
when multiple externals are collecting mail off the same
postoffice, they both can collect the same mail item and
successfully deliver it to the same recipient.
Version 3.2 of External resolves this by locking the mailbags
before the collection process begins. As a result overall
throughput of a multi-External hub will be faster because each
external will not try and collect mail on one postoffice while
another external is collecting mail on the same postoffice.
1678 External: Postoffices on dynamic drives updates lists at every
-U minutes.
In version 3.2 of External, directories on dynamic drives
are only updated at the interval specified by -U, if the
postoffice directories have been changed since the last
update. The change is detected by checking to see if the
value in FLAG.GLB has changed since last update.
1775 External: Zero length attachments.
When remote users call into version 3.0 External and request
headers update only when they do not have any headers,
External will create a zero byte attachment and leave it
stranded when the remote user disconnects. Version 3.2 of
External resolves this by deleting the attachment file upon
the disconnect.
2008 DirSync: Srvmain has problems with Intel EtherExpress 16.
With certain network cards and protocols, the SRVCONF.GLB
file becomes corrupted. Version 3.2 fixes the problem by
making internal buffer size consistent across all calls to
SRVCONF.GLB.
2082 Re-enabling the DirSync Server does not work.
In version 3.2, when re-configuring or creating a postoffice
to be a Dir-sync server the Admin program will now verify
that the REQCONF.GLB file has a srvsync value of zero. If
Requestors do not submit an Import request to the newly
enabled Server PO then they will not get updates. This is
because, each Requestor records the sync of the last update
received from the Server PO. This is a non-zero value. When
the Server PO is enabled, updates are numbered from 1. So,
if a Requestor asks for updates from sync=100, 100 will not
exist yet and that Requestor will receive zero updates.
2104 External: Does not delete .P0x files from the P1 directory.
Version 3.0 External can leave stranded .POx files.
2128 External returns valid address messages to sender.
When version 3.2 External is aware that it has corrupt
routing information, it will disable Dispatch for that PO and
its INQUEUE3.MBG. Mailer will still run on the destination PO,
but External will hold all LAN mail until the address list
is refreshed.
MAIL FOR WINDOWS CORRECTIONS
Bug # Description
----- --------------------------------------------------------------
1 Corruption of MMF when located on PC-NFS file server.
When running version 3.0b of Microsoft Mail for Windows on a
PC-NFS file server, the Mail Message File (MMF) becomes
corrupted and prevents you from sending and reading mail
messages.
2 Setup error when installing client on network server.
When setting up version 3.0b of Microsoft Mail for Windows
and the WINDOWS and WINDOWS\SYSTEM directories were on two
different drives, Setup would report an error and would not
complete.
3 Problem with extended characters in postoffice name.
When you send mail to an external postoffice group or gateway
group that contains extended characters in the address, version
3.0b of Microsoft Mail for Windows does not convert from code
page 850 to ANSI code page when it reads the records from the
NETPO.GLB file or any other gateway address file.
4 Convert program cannot handle lowercase HEX for owner field.
While converting your folders, version 3.0b of CONVERT.EXE
may report a network error and then exit. The Convert program
assumes the owner field in the .IDX file is in all uppercase
letters and does not know how to handle hexadecimal numbers in
lowercase letters.
5 Sample Microsoft Visual Basic for Windows application does
not work with Visual Basic version 2.0.
In version 3.2, MAPI.H has been modified to be strictly ANSI
compatible, and will no longer cause warnings on Warning
Level 4 with the Microsoft C version 7.0 compiler. The sample
Visual Basic Simple MAPI application has been modified to
compile when using Microsoft Visual Basic version 2.0.
6 SNADS DGNs in address book are not in alphabetical order.
External postoffices, SNADS DGNs, and nodes for PROFS and
OfficeVision are not displayed in alphabetic order because
version 3.0b of Mail for Windows reads them in one at a
time and adds them to the hierarchy. Version 3.2 of Microsoft
Mail for Windows reads them in all at once, sorts them, and
adds them to the hierarchy.
7 ALT+double-click on attachment does not work.
When you attempt to launch attachments that do not have an
extension, an error occurs when you hold down the ALT key
and double-click the mouse button to load the attachment
into Notepad.
26 Bad algorithm for changing the filename of Macintosh file
attachments.
When you attempt to launch MACBINARY attachments, version
3.0b of Mail for Windows changes the filename of the file
being launched if that filename is less than eight characters
in length.
69 Cannot handle more than 66 different network/gateway names.
An "Unknown user" error may occur when you send a message.
Version 3.0b of Mail for Windows only caches the first 8170
bytes of the NETWORK.GLB file and loses the rest. Postoffices
and gateways that are defined past 8170 bytes are ignored;
therefore, you cannot send messages to the users on those
postoffices or gateways.
73 MAPILogon is case sensitive.
The simple MAPI command MAPILogon() does a case sensitive
match on the user name and password; however, Microsoft
Mail is not case sensitive. This problem only occurs if a
MAPI session was already established when MAPILogon() is
called.
110 Reading E-Form from shared folder causes MAPI failure.
Fixed in version 3.2 of Microsoft Mail for Windows.
140 MAPISaveMessage resets originator to caller.
Fixed in version 3.2 of Microsoft Mail for Windows.
141 Convert changes message date to 12/16/68.
When parsing old A.M./P.M. style dates (generated from
some gateways), version 3.0b of Mail for Windows adds 12 to
the time if it is P.M. However, if the message was sent
during the Noon hour, the time is incorrectly read as 24:xx.
Because this is an invalid time, the date is set to the
12/16/68.
149 Group name cannot display details when a form was used.
In version 3.0b of Microsoft Mail for Windows, PC Mail
groups would not be reply-able from SimpleMAPI as the
address would have no email address.
161 SENDFILE does not support extended characters.
In version 3.0b of Microsoft Mail for Windows, extended
characters are not supported when using the File Manager
SendFile command. An error message is displayed saying
that the file can not be accessed.
162 Extended characters not supported for backup.
In version 3.0b of Microsoft Mail for Windows, extended
characters are not supported for *.MMF filenames.
176 GP fault when running custom setup and only installing
spelling.
Fixed in version 3.2 of Microsoft Mail for Windows.
187 GP Fault when login due to corrupt .XTN file.
Version 3.0b of Microsoft Mail for Windows may cause a
general protection (GP) fault when it encounters a
corrupt .XTN file in the database. It incorrectly handles
.XTN files that are an incorrect size.
