It's not a very common request these days, but does anyone know of any really good strategy games with play-by-email functionality?

I've been looking for a little while after I noticed that Crimson Fields (an open source Battle Isle-style game which I installed on my SUSE Linux laptop) has the option.

On a different note, I am a great fan of Racer, the free car simulation, but are there any more free/abandoned racing games with internet play?
The smaller the download the better.

Thanks for any replies in advance.
