Run SpamAssassin or similar as a milter from Postfix.

One hint that may help is that on many lists there's a short list of
keywords that allow you to whitelist content when they appear in a
text/* part.  Eg, on Python lists, almost no spam contains the word
"python" (except perhaps in the greeting "Dear
[email protected]").  SpamAssassin and similar filters allow you
to add rules for this kind of thing.
