SMTP: Microsoft Mail SMTPGATE.EXE Version 3.0.9 Update

ID: Q101461

The information in this article applies to:
  • Microsoft Mail Gateway to SMTP, version 3.0
Microsoft provides SMTPFTP.EXE, SMTPLMN.EXE, SMTPNVL.EXE, and SMTPWIN.EXE, which replace the SMTPGATE.EXE file that is included with version 3.0 of the Microsoft Mail Gateway to SMTP.

For complete information about obtaining and installing the SMTP program files, see the following sections:

  • To download the updated files


  • To update your SMTPGATE.EXE file



MORE INFORMATION

Version 3.0.9 of the Microsoft Mail Gateway to SMTP requires a dedicated 80286, 80386, or 80486 IBM-compatible computer as well as version 3.04.1 or later of the SMTPPUT.EXE file, update included in PUTUPD.EXE on the MSL. To determine your version of SMTPPUT, run it from the MS-DOS prompt with the -VER option.

This update contains SMTPFTP.EXE, SMTPLMN.EXE, SMTPNVL.EXE, SMTPXLN.EXE, and SMTPWIN.EXE, which replace the SMTPGATE.EXE file that is included with version 3.0 of the Microsoft Mail Gateway to SMTP. These replacement files correct the following problems:

  • The gateway does not generate greetings (HELO) that include the gateway computer host name. This problem occurs when you communicate with an IBM VM host running IBM VM SMTP V2R2. (This problem was originally corrected in the SMTPGATE.EXE 3.0.2 update.)




  • The gateway closes the connection after an Extended HELO (EHLO) message is received from another SMTP host as explained in RFC 1425, SMTP Service Extensions. There may still be a problem if the host sends an RSET after you refuse the EHLO message, which is recommended in RFC 1425, but is not consistent with RFC 821. (This problem was originally corrected in the SMTPGATE.EXE 3.0.2 update.)


  • The recipient field is constructed incorrectly whenever the friendly name information is included directly in the address of the recipient. As a result, the address is in the form:
    <<username>@<domain> (<friendly name>)>
    However, per RFC 822, the comment should not be included within the angle brackets. (This problem was originally corrected in the SMTPGATE.EXE 3.0.5 update.)


  • When the gateway strips non-SMTP gateway addresses from the message header, a false end-of-header marker is created in the RFC 822 portion of the message. This causes the date and subject fields, as well as the remaining recipients, to appear in the body of the message. (This problem was originally corrected in the SMTPGATE.EXE 3.0.7 update.)

    NOTE: Only the updates for the PC/TCP Kernel from FTP Software, Inc., and Microsoft LAN Manager for MS-DOS are included with this update.


  • The gateway does not allow the default character set translations to be overridden. If the two files SMTPIN.TBL and SMTPOUT.TBL exist, the gateway can do character translation for one of the following character sets instead of for the US-ASCII character set, which is used when these files do not exist: Swedish/Finnish, Norwegian/Danish, German, Latin Alphabet 1, and Code Page 850. (This problem was originally corrected in the SMTPGATE.EXE 3.0.6 update.)


  • The gateway improperly processes comments as addresses if a comma appears in the comment.




  • The gateway improperly rejects an RFC 822 address it has previously accepted in the RFC 821 portion of a message.




  • The gateway saves the From field seen in the envelope part (RFC-821) of an incoming message to use in case the Microsoft Mail recipient wants to reply to the message. (This problem was originally corrected in the SMTPGATE.EXE 3.0.9 update.)


For additional information, please see the following article in the Microsoft Knowledge Base:
Q99713How Reply Chooses a From Address
  • The gateway does not include the host names in its greeting replies. (This problem was originally corrected in the SMTPGATE.EXE 3.0.1 update.)

To update your SMTPGATE.EXE file

At the MS-DOS command prompt, type the following and press ENTER
copy <path>:\<smtp???>.exe <destination>\smtpgate.exe
where <path> is the drive and directory where you ran the self- extracting SMTPGW.EXE file, <destination> is the drive and directory where your SMTPGATE.EXE file currently resides, and <smtp???> is the corresponding executable file for your TCP/IP software vendor.

For example, if you ran the self-extracting file from the TEST directory on drive D, your SMTPGATE.EXE file is located in the MAILEXE directory on drive C, and you are using Microsoft TCP/IP for LAN Manager, type the following command and press ENTER:
copy d:\test\smtplmn.exe c:\mailexe\smtpgate.exe
NOTE: The SMTPGATE.EXE file typically resides on the postoffice server in the Mail executables directory as well as on the machine where the gateway is running. Make sure that SMTPGATE.EXE, SMTPGET.EXE, and SMTPPUT.EXE are all located in the same subdirectory where the gateway is launched from and that all copies are updated appropriately.

To Set Up Character Translation for Non-US-ASCII Character Set

  1. Decide which character set is desired. The following is a list of the character sets, associated filenames, and references that are located on the disk provided with this update: 
    
   Character set    | Inbound      | Outbound    | Reference
   -------------------------------------------------------------
   US-ASCII         | Built in     | Built in    | ANSI X3.4
   Swedish/Finnish  | SWEDISHI.TBL | SWEDISHO.TBL| SIS 63 61 27
   version 2        |              |             | (ISO-646-SE2)
   -------------------------------------------------------------
   Norwegian/Danish | NORWEGI.TBL  | NORWEGO.TBL | NS 455
   version 1        |              |             | (ISO-646-NO)
   -------------------------------------------------------------
   German           | GERMANI.TBL  | GERMANO.TBL | DIN 66003
                    |              |             | (ISO-646-DE)
   -------------------------------------------------------------
   Latin Alphabet 1 | LATIN1I.TBL  | LATIN1O.TBL | ISO 8859-1
   -------------------------------------------------------------
   Code Page 850    | Built-in     | CP850O.TBL  | IBM
                    | default      |             |
    NOTE: If SMTPGATE.EXE does not find the SMTPIN.TBL and SMTPOUT.TBL files, the built-in default tables are used.


  2. At the MS-DOS command prompt, type the following and press ENTER
    copy <path>:\<??????i.tbl> <destination>\smtp\smtpin.tbl
    copy <path>:\<??????o.tbl> <destination>\smtp\smtpout.tbl
    where <path> is the drive and directory where you ran the self- extracting SMTPGW.EXE file, <destination> is the drive and directory where your Microsoft Mail postoffice data files currently reside, and <??????i.tbl> and <??????o.tbl> are the corresponding inbound and outbound character table files.

    For example, if you ran the self-extracting file from the TEST directory on drive D, your Microsoft Mail postoffice is located on drive M, and you are using the German translation table, type the following commands and press ENTER after each command:
    copy d:\test\germani.tbl m:\smtp\smtpin.tbl
    copy d:\test\germano.tbl m:\smtp\smtpout.tbl
    Make sure you have updated the SMTPGATE.EXE file to version 3.0.7 or later; otherwise, the character translation won't take place.


Translation Details

Inbound messages have the subject and text body translated based on the SMTPIN.TBL file. Friendly names are not translated.

Outbound messages have the subject and text body translated based on the SMTPOUT.TBL file. Friendly names are translated based on an internal table that maps extended characters to a 7-bit equivalent.

NOTE:

  • Only 7-bit characters are supported in a Microsoft Mail address, which consists of the network name, postoffice name, and mailbox ID.


  • The tables for national 7-bit character sets (Swedish/Finnish, Norwegian/Danish, and German) will convert characters with character codes above 127 according to Latin Alphabet 1 for inbound messages. That is, they will accept national characters (F, V, and so forth) according to both 7-bit and 8-bit standards.


Gateway Operation

Informational messages are displayed on the screen and in the SMTP gateway log file when you use the -CD (debugging), -LACSY (full logging to SMTPGATE.LOG), and/or -GACSY (full logging to the SMTPGATE screen) options when you start up the gateway.

If the SMTP translation files are not found, the following messages are displayed:

18:02:40 - Open File <f:smtp\smtpin.tbl> failed,
No such file or directory
18:02:40 - f:smtp\smtpin.tbl table not loaded,
default translation invoked.
18:02:40 - Open File <f:smtp\smtpout.tbl> failed,
No such file or directory
18:02:40 - f:smtp\smtpout.tbl table not loaded,
default translation invoked.
If the SMTP translation file(s) are found and can be loaded, the following messages are displayed:
11:19:09 - f:smtp\smtpin.tbl table translation loaded.
11:19:09 - f:smtp\smtpout.tbl table translation loaded.
If problems with a translation file are detected, the default translation message and one of the following messages are displayed:
18:02:40 - File <f:smtp\smtpout.tbl> header size invalid.
18:02:40 - File <f:smtp\smtpout.tbl> translation checksum invalid.
18:02:40 - File <f:smtp\smtpout.tbl> translation table size invalid.
