PC Ext: Support of EXTERNAL.EXE Under Windows NT (118620)

SUMMARY

This article describes the support of both the Microsoft Mail Message Transfer Agent (MTA) and the Microsoft Mail Multitasking MTA (MMTA) version 3.2 running under Microsoft Windows NT versions 3.1 and 3.5. The program name for both the MTA and the MMTA executables is EXTERNAL.EXE.

NOTE: This article does not apply to version 3.5 of Microsoft Mail Multitasking MTA for Windows NT.

MORE INFORMATION

The following is a summary of the support of the MTA and the MMTA under Windows NT 3.1 and 3.5:

The Multitasking MTA for Windows NT Server (NT MMTA) was created to replace running the OS/2 Multitasking MTA on Windows NT. It is strongly recommended in this configuration to upgrade to the NT MMTA. Advantages gained by upgrading to the NT MMTA include:

Running External as a Windows NT service.
Asynchronous message transfer up to 28800 baud with supported modems.

The NT MMTA requires that you are running Windows NT Server version 3.51, and is not supported on Windows NT Workstation.

Supported Under Windows NT

The MMTA doing LAN-based transfers only under Windows NT operating system.

Not Supported Under Windows NT

The MTA is not supported under any circumstances under Windows NT.

The MMTA is not supported doing asynchronous transfers because the MMTA must access hardware directly, and this is not possible under Windows NT. Transferring via X.25 is not supported either for the MMTA on Windows NT, as there was not an X.25 driver for Windows NT.

For systems connecting to Novell NetWare versions 3.x and 4.x using Microsoft Client Service for NetWare, dynamic drive connections are not supported. This is because the MMTA using dynamic drive connections uses the OS/2 NetWare APIs, which are not supported under Microsoft Client Service for NetWare under Windows NT.
