I spent some time looking how to install Spam Assassin, so I'll share my experience.

First of all we have to use ‘JAM Software’ package : others may discontinued.

Here is the link : http://www.jam-software.com/spamassassin/

 

Go to c:\program files\JAM software\SpamAssassin for Windows and launch SpamD.exe

A DOS console will stay open. If you have a firewall add spamd.exe in exceptions.

Then open ArGoSoft Mail Server and choose Security, Anti spam, SpamAssassin. Check enabled and click on Test. A message will say « service appears to be responding »

 

 

Close spamd.exe console window.

The configuration file is in c:\program files\JAM software\SpamAssassin\share\v3.xxxxxx\updates_spamassassin_org\local.cf

For paramaters see SpamAssassin website or use this generator : http://www.yrex.com/spam/spamconfig.php

 

Download NSSM : http://iain.cx/src/nssm
Copy nssm.exe in your system32 folder

Open a command prompt and type :

Cd\
Cd windows
Cd system32
Nssm.exe install SpamAssassin

Click on Browse and choose Spamd.exe
Click on Install Service

Restart your server or start service manually for the first time.

 

All done !
