Is SA able to make text version of the HTML part? It only needs to perform good 
on non-spam.

Then you have the problem of determining if the two texts are different.

That problem can be solved with the Levenshtein Distance, it's described on 
http://www.merriampark.com/ld.htm

It tells you how much you have to change to make the texts equal.

The algorithm is O(n^2) so it should probably only be run on the first few kb of 
the mail or something like that.
