M-Switch is a high-performance, flexible and robust Message Transfer Agent (MTA) that can be configured to act as an SMTP, X.400 or MIXER MTA. Isode messaging products, including M-Switch, have special functionality to optimise operation over constrained bandwidth links (such as HF and SatCom).

More information on M-Switch SMTP and M-Switch X.400 is available on this website, as is a general overview of Isode's Applications for Military Radio and Satellite.

Who is this evaluation for?

This evaluation guide is intended for those wishing to set up Isode's M-Switch server to run over constrained links using the ACP 142 protocol to carry one of two types of messaging traffic:

  • X.400 traffic according to STANAG 4406 Annex E.
  • SMTP traffic using BSMTP encoding and STANAG 4406 Annex E compression.

By "constrained links" we mean setting up M-Switch to operate over an IP network (such as SatCom or IP over radio links) or HF Radio using STANAG 5066 (the NATO standard for data applications over HF radio).

Evaluation Objectives

At the end of this evaluation you will have set up a two-node ACP 142 system. The evaluation guide covers system setup for operation over IP and over STANAG 5066. Instructions for setting up EMCON (Emmission Control) states for nodes are also given. Although this guide recommends you start your evaluation by setting up a two-node system, this guide can also be used to connect two or more ACP 142 systems over a multicast network.

Getting Started

You will need download the program files using the links below. Downloads require an evaluation password, if you do not already have one you can request one using this short form. You can download the evaluation documentation without logging in.
