SA on Windows XP + POP to desktop client?

[Lee]

Hello SpamAssassin fans,
Having read and tried various things on the SA site and elsewhere, even 
including some technically dead stuff in the Web Archive, I'm wondering 
if anyone knows how to achieve the following set up (for free) and is 
willing to share it :-

Install the latest SpamAssassin 3.2.5 (or at least 3.2.4) on Windows XP, 
whether that be in a convenient point-and-click .exe manner or the more 
complex procedure of installing Active Perl, making SA, etc in the 
command line
and importantly
a method to pass incoming POP emails through SA on the way to a desktop 
email client such as Thunderbird.

I'm currently achieving the above using a very nice program called 
SAwin32 on Sourceforge, which uses SA 3.2.3 and is almost two years old. 
It doesn't offer the entire functionality that SA is capable of, but 
appears to work fine. However, the project appears to be discontinued 
and I have no idea if it can be updated to run a newer SA version.

Thanks in advance if you can help; of course very specific build details 
may be required for others like me to be able to set it up successfully. 
I also appreciate some parts/modules of SA may not be workable on Windows.
